Insertion of a dc-dc converter between the automobile battery and electrical loads is proposed. This would allow gradual conversion to higher battery voltage, regulation of dc distribution voltage, and multiple distribution voltage levels. Switching loss arising from parasitic inductances is a serious problem in this application. The nonlinear resonant switch can remove this source of loss, ach...

This paper proposes an analytical approach to derive voltage gain for phase modulated (PM) dc-dc series resonant converter (SRC) operating in discontinuous conduction mode (DCM). Conventional fundamental harmonic approximation (FHA) technique is extended for non-ideal series resonant tank. The DCM analysis is presented in a normalized form defining appropriate base quantities. The converter is ...

Constant-current (CC) power supplies find applications in many fields. The Resonant immittance converters (RICs) convert a voltage source to the current source, thereby render them suitable for its application as a CC power supply. A fourthorder RIC topology, TT44 , is studied in this paper. Detailed steadystate analysis is presented. Procedure to perform converter optimization that leads to cl...

This work is about the analysis of dead time variation on switching losses in a Zero Voltage Switching (ZVS) synchronous buck converter (SBC) circuit. In high frequency converter circuits, switching losses are commonly linked with high and low side switches of SBC circuit. They are activated externally by the gate driver circuit. The duty ratio, dead time and resonant inductor are the parameter...

In this paper an asymmetrical duty cycle control strategy was proposed to the TPTL dc/dc converter. The modified converter remains all the advantages of original control strategy; meanwhile, soft-switching can be achieved using the energy stored in output filter inductance and leakage inductances of transformers (or resonant inductances).Three-phase three-level (TPTL) dc/dc converter has the ad...

The multi-phase implementation in the QR (quasi resonant) ZCS (zero current switching) SC (switched capacitor) bidirectional DC-DC converter structure has been proposed to reduce current ripple, switching loss and significantly increase the converter efficiency and power density. This approach provides a more precise output voltage to obtain voltage conversion ratios from the double-mode versus...

This document describes several aspects relating to the design of dc-dc converters operating at frequencies in the VHF range (30-300 MHz). Design considerations are treated in the context of a dc-dc converter operating at a switching frequency of 100 MHz. Gate drive, rectifier and control designs are explored in detail, and experimental measurements of the complete converter are presented that ...
