“…The systems in [25], [26], offer a fast transient response because power balance control techniques were applied in the voltage control loop. The power balance was considered at the AC input power source of the converter and the DC bus of the output voltage.…”

The redundant operation of a parallel AC to DC converter via a serial communication bus is presented. The proposed system consists of three isolated CUK power factor correction modules. The controller for each converter is a dsPIC30F6010 microcontroller while a RS485 communication bus and the clock signal are used for synchronizing the data communication.The control strategy of the redundant operation relies on the communication of information among each of the modules, which communicate via a RS485 serial bus. This information is received from the communication checks of the converter module connected to the system to share the load current. Performance evaluations were conducted through experimentation on a threemodule parallel-connected prototype, with a 578W load and a -48V dc output voltage. The proposed system has achieved the following: the current sharing is quite good, both the transient response and the steady state. The converter modules can perform the current sharing immediately, when a fault is found in another converter module. In addition, the transient response occurs in the system, and the output voltages are at their minimum overshoot and undershoot. Finally, the proposed system has a relatively simple implementation for the redundant operation.

“…Also, it incorporates indirect method of control of the load voltage and the need of capacitance of high value to be connected in parallel to the output. Single-phase rectifier used in three phase converter, which converts AC to DC, and its parallel operation is presented in [14]. The system has better transient response because of the dynamic feature in the control technique.…”

A modular structured and high efficient photovoltaic (PV) system is essential in today’s scenario. The single stage Cuk based inverter has continuous input and output current, and hence, makes it suitable for applying MPPT techniques when used for PV applications. The PI, PID, and fuzzy controllers could be applied for PV inverter. The PI controller decreases the error in steady state, and at the same time, it also decreases the stability of the system. The PID controller involves large time delay process. The random nature in fuzzy controller may not lead to optimum results. Hence, this paper proposes a controller based on Adaptive Neuro-Fuzzy Inference System (ANFIS) for a three phase PV inverter based on Cuk converter. The effectiveness of proposed system is verified using MATLAB/SIMULINK, and the results are presented. The performance of proposed ANFIS controller for Cuk based three phase inverter is compared with conventional PI controller. The proposed system has several merits like increased performance, accuracy, and efficiency.

“…In addition the standby power consumption had to be reduced to 0.5 W after 6th January 2013 and to 1 W for electronic home appliances that support display, remote control or WOL functions. To reduce the standby power consumption there has been much research focusing on the circuit design, modifying the architecture of the power consumption or increasing the power factor to improve the efficiency of the AC-to-DC power regulator [22][23][24]. Some other ways that can be used to improve the efficiency of pulse width modulation of the DC-to-DC power regulator are either the zero voltage switching (ZVS) or the zero current switching (ZCS) method; these methods focus on circuit modification to improve both the ZCS and the ZVS to reduce switching loss [25,26].…”

Most previous low-power personal computer designs have been either focused on power efficiency improvement or on software power management in the working states. This research aims to reduce the total standby power amount in the off state. The authors accomplish the goal of reducing the power consumption by a wake-up device which is replaced by a chip with a still lower consumption. The authors redesign the power circuit and cut off the power supply for the unnecessary chips, with the exception of the power needed for the specific chip used to wake up the system. The authors also turn off the power supply of the original power controller chip which is used to control the system's power status. In addition, the authors use another low-power chip instead of the original one and redesign the power sequence of the system in order to maintain the system's power state while the system's power status controller is turned off. Finally, as the authors use this low-power chip to manage the standby power source separately by means of the remote wake-up devices, the authors reduce further the standby power consumption to 4.4 mW in the power-off state by use of the various wake-up methods. The total result is an improvement of approximately 99.3%.
