“…Various techniques have been proposed in literature to run the machine efficiently over a larger speed range, for instance, series capacitance tuning in [7], current phase angle variation with constant frequency in [8], and two-phase excitation in [9][10][11]. Similarly, multiple circuit topologies have been discussed in [12] for two-phase excitation of the SPPSCIM. We have selected a semi-full bridge PWM inverter with a boost converter [13] for our implementation.…”

Large HVAC systems are good candidates for elastic loads in demand side management optimization of smarter grid infrastructures. There is an increaseing trend of using Split-type Air Conditioners (ACs) in residential, commercial and industrial setups for fine granularity temperature control. The traditional control in each unit is through duty-cycle based hysteretic method which is simple but inefficient and requires power spikes at every start-up of the compressor. In developing countries with weak grids, people rely on backup sources like generators and UPS. Large power surge at each turn-on inflicts huge pressure on these constrained resources. Limited work has been reported that aims at energy optimization and controlled operation of Splittype ACs constructed using single phase permanent split capacitor induction machine (SPPSCIM). Our work targets operational optimization, efficiency enhancement and increased load handling capability of contrained power systems in setups employing multiple AC units. This is done through networked Variable Frequency Drives (VFD) for conventional ACs which allow elimination of surge current at turn-on and tighter setpoint control while drawing sinusoidal current near unity power factor from the constrained source. Furthermore, the networked operation allows integration of existing installed base of standalone units through Building Management System (BMS) with the central control infrastructure. The prototype networked VFD is tested on a 2.3kW Mitsubishi Electric Split-type AC through Wi-Fi and the results are presented to confirm the expected results in network mode of operation.

This research discusses about vector control of single-phase Induction Motor (IM) with two main and auxiliary windings under stator winding open-phase fault based on Indirect Rotor Flux-Oriented Control (IRFOC). IntroductionSingle-phase Induction Motor (IM) is one the most commonly IMs which is used in washing machines, drills, compressors, refrigerators, pumps, dryers and many other applications. A single-phase IM is principally an unbalanced IM since it is constructed with two unequal main and auxiliary windings [1].AC drives of single-phase IM demonstrate better performance, lower protection, improved reliability and are cost-benefit in comparison with their DC counterparts [2,3]. In the literature, numerous studies have been conducted on Variable Frequency Control (VFC) techniques of single-phase IM drives such as scalar and vector control techniques. These control techniques assure energy saving, improved efficiency, decrease in torque response pulsation and etc [4][5][6][7][8]. Recent research trend on IM is toward vector control of single-phase IMs or unbalanced two-phase IMs [9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Generally, in all proposed vector control methods for single-phase IMs, the start-up and running capacitors are disregarded and single-phase IM is considered as an asymmetric 2-phase IM. Use of hysteresis current controller for Field-Oriented Control (FOC) of unbalanced 2-phase IM has been suggested in [9]. In [10], FOC technique for a single-phase IM with current double sequence controller for decreasing the torque pulsation has been proposed. Using current double sequence controller is a complex controller due to using many PI controllers. To solve problems in [9,10], in [11,12], decoupling vector control of single-phase IM has been presented. In [11,12], by introducing two new decoupling signals in addition to the decoupling signals like ones used in 3-phase IM, a novel technique for vector control of single-phase IM based on FOC has been proposed. However, decoupling vector control technique depends on variation of single-phase IM parameters. In [13][14][15][16][17][18][19][20][21][22], some methods for high performance FOC of single-phase IM or unbalanced 2-phase IM have been presented which can be listed as follows; In [13][14][15][16], speed sensorless Indirect FOC (IFOC) of 2-phase IM using Extended Kalman Filter (EKF), in [17], Model Reference Adaptive System (MRAS) observer for rotor speed estimation, in [18], sensorless FOC of single-phase IM with on line stator resistance estimation, in [19,20], two techniques for speed sensorless IFOC of unbalanced 2-phase IM based on motor model, in [21], FOC of 2-phase IM using Genetic Algorithm (GA) for speed PI controller tuning and in [22], Virtual High Frequency Injection Method (VHFIM) to determine the speed and position in IFOC of 2-phase IM have been presented.

“…The voltage obtained from (18) for the modified SEPIC converter is always lower than the switch voltage of the classical boost and SEPIC converters because the input voltage is always lower than the output voltage in the modified SEPIC converter. Considering the operation at steady state and the average voltage across the inductors is equal to zero, the theoretical waveforms presented in Fig.3.8 shows that the positive area of the inductor voltage must be equal to the negative area as presented in (19) for the inductorL 1 .…”

The request for developing power quality of the AC system has drawn excessive interest during the recent years. The increased usage of power electronic devices, such as variable speed drives, uncontrolled rectifiers and other switching devices, affects the power quality of the utility grid significantly. The SEPIC converter is selected because of its numerous advantages over buck, boost and buck-boost converter. The bridgeless SEPIC converter has numerous advantages compared to the ordinary bridge converter. It reduces the complexity of the control circuit, can be easily implemented. The SEPIC converter operating in continuous conduction mode is explained in this paper. This SEPIC converter is capable of giving high power factor and low harmonic distortion. The implementation of this Bridgeless model in the SEPIC converter operating in Discontinuous conduction mode is the main outcome of my project and how it works. Applications: Balanced three phase equipment and single phase equipment, portable power tools, All lighting equipment, single phase (below 600W). Keywords: Discontinuous conduction mode (DCM), Pulse width modulation (PWM), Voltage source inverter (VSI), Simulation I.INTRODUCTION Development in the field of POWER ELECTRONICS is quick and appreciable. These developments have increased the nonlinearity of the electrical system. With increasing quantities of non-linear loads being added to the electrical systems, it has become necessary to maintain the power quality. The problems related power quality becomes an issue of concern. If electrical equipment operates correctly and reliably without being damaged or stressed, then the electrical power is of good quality. Power quality determines how efficiently the power is utilized by the consumer devices. Poor power quality can be described as any event related to the electrical network that ultimately results in a financial loss and reduce the life of the appliance connected to the supply of poor quality. The induction motors are the commonly used motor in household appliances because of its rugged construction and low cost. The major problem associated with the induction motors are the low power factor and the high harmonic distortion. The power factor was found to be 0.667 and a huge amount of power is being wasted up and this affects the quality of power. The main objective of the project is to improve power factor and to reduce ripples in the input current and also to provide an efficient speed control method. The proposed system is used for the single phase induction motor in ceiling fan or refrigerator. Normally the speed control of the single phase induction motor is done using triac. This is not an energy efficient technique as huge amount of energy is wasted in the speed control of induction machine. The above mentioned problem is overcome by means of a PFC SEPIC converter which operating in DCM and a PWM control technique is used for the smooth speed control of the induction machine. As a result the problem related to power factor and har...
