Most of the power electronic equipments are operated with dc supply. For reliable and stable operation, dc supply should be regulated. The regulation can be performed using buck, boost, Cûk, Sepic, Flyback regulators. Except single phase rectifier with resistive load all other rectifiers input currents are non sinusoidal in nature. This front end current distortion of rectifier converter leads ...

A new fuzzy maximum power point tracker (MPPT) for photovoltaic systems is proposed. Fuzzy controller input parameters dI dP , ) dI dP ( D and variation of duty cycle ( DC D ) are used to generate the optimal MPPT converter duty cycle, such that solar panel maximum power is generated under different operating conditions. A photovoltaic system including a solar panel, a fuzzy MPP tracker and...

This paper introduces a bi-directional DC-DC converter with adaptive fuzzy logic controller (AFLC). Bi-directional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains, the converter operates as buck converter, powers the down stream converter, and also charges the battery. When the DC mains fails,...

Dynamic voltage scaling (DVS) can effectively reduce energy consumption by dynamically varying the supply voltage of the system accordingly to the clock frequency. A new DVS-enabled DC–DC converter is presented in this paper. State trajectory is employed to analyze the transient features of PWM and PFM Buck converters. A novel transient enhancement circuit is designed to improve the transient r...

Switched Boost Inverter (SBI) is a single stage DC to AC power converter and it is derived from the Z source inverter employs an LC impedance network in between the main inverter bridge and the power source. This SBI converter can possible to supply both DC and AC loads simultaneously from a single dc input source. Here, reducing the inverter switching stress. Also, this converter provides to s...

Zero Voltage Transition (ZVT); Zero Current Transition (ZCT); Synchronous buck converter (SBC); Pulse width modulation (PWM) Abstract In this paper, a Zero-Voltage-Transition (ZVT)–Zero-Current Transition (ZCT) Pulsewidth Modulated (PWM) synchronous buck converter (SBC), with a simple passive auxiliary circuit is proposed, which reduces the stresses and improves the efficiency by pacifying the ...
