This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

The inherent nature of normal boost converter has more voltage stress across the power electronics switch and ripple. The presented formation of the front end rectifier stage for a photovoltaic (PV) organization is mainly used to give the supply. Further increasing of the solar efficiency is achieved by connecting the zero voltage soft switching boost converter. The zero voltage boost converter...

A new zero voltage switching current fed zero-voltage switching isolated boost converter topology for fuel cell applications is presented. L-type half-bridge is more suitable to low voltage, high current applications such as front-end dc–dc converters for the fuel cell applications. It has larger switch voltage rating and also suffers from high voltage across the switches. Clamping methods are ...

A novel ZVZCS isolated dual series-resonant active-clamp dc–dc converter is proposed to obtain high efficiency. The proposed converter employs an active-clamp technique, while a series-resonant scheme controls the output voltage with the complementary pulse width modulation controller. The active-clamp circuit serves to recycle the energy stored in the leakage inductance or the magnetizing ...

To achieve the soft-switching condition and stabilize the output voltage of quasi-resonant converters, the paper proposes a double closed-loop control method (DCCM). In the inner loop, soft-switching is guaranteed with the off-time of the switch determined by the zero-crossing signal of the switching voltage. In the outer loop, the output voltage is regulated to be constant against load variati...

Zero voltage switching (ZVS) is useful to increase power electronics efficiency but difficult achieve due the non-linear parasitic capacitance of semiconductors and varying load current. This letter proposes a self-adaptive ZVS method by using intrinsic electroluminescence (EL) property SiC MOSFETs automatically adjust frequency in every cycle retain optimal A sensing circuit developed digitall...

This paper introduces a new soft switching boost converter with passive snubber. In the proposed converter, the main switch turns on under zero current switching (ZCS) and turns off under zero voltage switching (ZVS) without any additional voltage or current stresses. The main diode turns on under ZVS and turns off under ZCS. The proposed converter has features as low cost, simple control, low ...
