A novel isolated zero-voltage-transition (ZVT) boost converter with coupled inductors is proposed in this paper to satisfy the high power, high step-up, and isolated requirements. In the proposed converter, the input-parallel configuration is adopted to share the large input current and to reduce the conduction losses, while the output-series structure is employed to double the output voltage gain...
A novel interleaved high step-up converter with voltage multiplier cell is proposed in this paper to avoid the narrow turn-off period and to reduce the large power device current ripple, which is existed in the conventional boost converters in high step-up applications. The voltage multiplier cell is composed of the secondary windings of the coupled inductors, the series capacitor and two diodes....
A new type of high step-up, high efficiency interleaved boost converter is proposed in this paper. Coupled-inductors are used in this topology to extend the duty cycle. Therefore, the low-voltage rated and low resistance devices can be applied to minimize the conduction which makes the conduction losses significantly reduced. ZCS turn-on is achieved by the intrinsic leakage inductance of the coupled...
This paper introduces a novel interleaved boost converter. By applying winding coupled inductors and switched capacitors in the output stage, the voltage gain of this topology is significantly increased and the voltage stress of the switch is greatly reduced so that the low conduction resistance and low voltage rated switches can be applied. Because of part of the output energy storing in the switched...
