This paper presents design of generalized resonant dc/dc converter with class E oscillator and a experimental result for low output Q and finite dc-feed inductance are shown. Low Q and finite dc-feed inductance is effective to minimize the circuit scale. Therefore, it is required to design the converter with any conditions, i.e., low output Q and finite dc-feed inductance. The experimental meas...

A new zero voltage switching (ZVS) dc / dc converter operating on constant frequency and having wide linearity is proposed. ZVS operations are achieved not only for the primary switches but also for the secondary rectifier diodes to reduce the switching stresses and losses. The proposed converter also overcomes the other shortcomings of the conventional resonant dc / dc converters such as high ...

To improve the energy quality, most of the renewable energy systems include an energy storage element charged by the bidirectional DC-DC converter. This paper proposes the bidirectional DC-DC converter which employs the two bridge configuration resonant class-E converters on the both sides of the isolating transformer. The low side converter is controlled as step up and the high side converter ...

The control of the input voltage of DC-DC converters is frequently required in photovoltaic applications. In this special situation, unlike conventional converters, the output voltage is constant and the input voltage is controlled. This paper deals with the analysis and the control of the buck converter with constant output voltage and variable input.

Purpose – To derive an analytical model for a dc-ac-dc parallel resonant converter operating in lagging power factor mode based on the steady-state operation conditions and considering the effects of a high-frequency transformer. Design/methodology/approach – A range of published works relevant to dc-ac-dc converters and their control methods based on pulse-width-modulation technique are evalua...

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of the non-isolation DC-DC converter to control the LED current and the light intensity, the conventional PWM DC-DC converter has the problem of low-power conversion efficiency. The half-bridge LLC co...

Multichannel resonant DC/DC converters have recently been popular in diverse fields, where multiple output voltage levels are required, such as supplying multilevel inverters. This paper is devoted to present the new member of a four-channel converter family, having consisted till now step down well step-up/down configurations. The capable realizing power flow amongst two input and four channel...
