Zvt-zct Pwm Dc-dc Boost Converter with High Efficiency
An improved active snubber cell is proposed for ZVT-ZCT PWM DC-DC boost converter. Zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off is provided by this active snubber cell. There is no extra current or voltage stresses on the main switch. Also, zero current switching (ZCS) turn on ZCT turn off is provided for the auxiliary switch. Although there is no extra volta...

In this study, a new boost converter with an active snubber cell is proposed. The active snubber cell provides main switch to turn on with zero voltage transition (ZVT) and to turn off with zero current transition (ZCT). The proposed converter incorporating this snubber cell can operate with soft switching at high frequencies. Also, in this converter all semiconductor devices operate with soft ...

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 ...
متن کاملAppendix A. The Novel ZVT and ZCT Soft-Switching Topology
Since the PCS needs to handle high power high voltage, the soft-switching topologies utilized in the design should have both ZVT and ZCT functions. A novel soft-switching topology that has both ZVT and ZCT functions is suggested. The new topology has both ZVT and ZCT functions by using two additional components, a switch and a diode. The auxiliary inductor for soft-switching is implemented insi...
متن کاملHigh Frequency Soft Switching Of PWM Boost Converter Using Auxiliary Resonant Circuit
This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequen...
