“…If the system is operating at a high value of M, then the lesser number of series modules has to be connected in series, ensuring the advantage of using high M. However, to increase output power, more arrays have to be introduced. Reference [26] suggests that at a high modulation index M, THD of output decreases as is evident from Table 2. This paper describes a novel modeling technique for standalone PV systems.…”

This paper proposes a technique for the energy management of a stand-alone photovoltaic system. The proposed system employs a power processing inverter that has a high PV voltage at the input to mitigate the magnitude of AC signal at the output, thus eliminating the use of DC-DC converter and reducing the input capacitor size of PV array. To meet the power requirement of load and to maintain the maximum power point operation of PV array, a battery bank is utilized with a bi-directional converter. An impedance model of the complete system is executed. Based on the model, the control architecture is designed which works in four modes: 1) if load demands > MPP of PV, additional current is extracted from the battery; 2) if load demands < MPP of PV array, extra current is given to the battery; 3) only load management is utilized since the battery bank is not available because of overcharging or under-charging; 4) if irradiation varies then the first mode is used for load requirement. The technique is designed which guarantees the maximum power point tracking of the PV system even without using any intermediate stage of a DC-DC converter, hence making it a single-stage system. MPPT is achieved by effectively controlling the bi-directional converter used for battery charging and discharging purposes. To ensure better utilization of dc voltage, enhanced efficiency, and low less harmonic distortion, a sinusoidal PWM technique is used to drive the inverter. Simulation results are carried out for ensuring better energy management along with MPPT operation demonstrated under uniform operating conditions.

A inverter is basically a device that usually converts DC to AC voltage without causing any power loss, applicable to only low to medium voltage applications. But in case of medium to high power applications, it has demerits like high switching losses, reduced cost and low efficiency. To overcome these demerits a Multilevel inverter applicable to high voltage and high-power applications which have low total harmonic distortion (THD) is introduced. This paper is mainly focused on seven-level inverter with five switches and four dc sources. with low total harmonic distortion, less switching loss without adding any complexity to the circuit. The switching topology is integrated with various SPWM techniques like Phase Disposition (PD), Phase Opposition Disposition (POD) and Anti Phase Opposition Disposition (APOD). For better performance of the inverter above three PWM techniques will be compared and analyzed to find the low THD configuration. The simulation of switching topology is done by MATLAB/Simulink.

There are two SP-PWM techniques for H-bridge inverter which are unipolar and bipolar switching [16] SPWM technique has reduced power loss, because of its switching devices remain almost off (Low current means low power) and remain hardly on (Low voltage, low power) PWM signals can easily be generated by using modern microcontrollers [17].…”

Abstract-This manuscript presents the effects of changing modulation indices on current and voltage harmonics of universal motor when it is supplied by single phase PWM (SP-PWM) inverter, the effect has been analyzed with simulation and experimental setup. For variable speed applications universal motor can be controlled either by phase angle control drive or by SP-PWM inverter drive. SP-PWM inverter-fed drive is common technique that is used to adjust the voltage applied to motor, so that variable speed can be obtained. With the application of SP-PWM inverter-fed drive, harmonics are generated because of power electronic devices. According to the IEEE standard 519, the total harmonic distortion (THD) must be within 5%. In this paper, the effect of modulation index (MI) is used to analyze THD content, and its variation alters the harmonic content. However, the effects are also analyzed through experimental setup in order to validate the system performance. In future work, keeping modulation index constant, different PWM strategies can be employed in order to decrease harmonics.
