There exists the problems of output voltage zero-point drift and high even harmonic content three-phase Cuk liftable photovoltaic (PV) inverter when it adopts conventional carrier modulation method. In view these, a new optimized Phase-Shifted Pulse Width Modulation (PSPWM) strategy is proposed. Firstly, optimal zero-sequence component determined based on topology control objectives. Next, inje...

As a nonlinear memory device, the memristor is often used as circuit load. In this paper, system based on traditional current-mode Cuk converter with voltage-controlled constructed. By deducing state equation of topology and continuous current mode equation, simulation model The dynamic characteristics are explored by using sequence diagram, phase diagram bifurcation diagram. addition, parametr...

A novel zero-voltage-transition (ZVT) pulsewidth modulated (PWM) Cúk power-factor corrector (PFC) is proposed to achieve unity power factor under zero-voltage-switching (ZVS) operations. In the proposed ZVT PWM Cúk PFC, not only the power switch, but also the power diode, commutate under ZVS. The proposed topology has the shortest ZVT time and, thus, the shortest minimum duty cycle compared wit...

Electric vehicles contain various types of light emitting diode (LED) devices. A significant twice-line-frequency ripple current is usually produced in a conventional offline LED driver with high power factor. In this paper, flicker-free based on isolated Cuk converter integrated magnetic technique proposed. Two inductors and transformer are combined into one core to eliminate the wave as much ...
