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...

This paper presents a robust passivity-based control (RPBC) strategy for half-wave zero-voltage switching quasi-resonant (HW-ZVS-QR) buck and boost type converters. The proposed controller is based on energy shaping damping injection. Theoretical analysis shows that the resulted closed-loop HW-ZVS-QRs are globally asymptotically stabilised even if physical constraint magnitude of signal taken i...

This paper explores the design of a Class-E amplifier with finite DC-feed inductance using three tuning methods. Furthermore, this work quantifies impacts process (referred to in as effect) on main figures merit (FoMs) amplifier. The goals were guarantee two conditions: zero voltage and derivative switching (i.e., soft-switching tuning). To best authors’ knowledge, systematic methods have not b...

Dual-active-bridge (DAB) converter is an attractive topology to be used as a dc transformer (DCT) in the power distribution system. Because voltage gain for relatively fixed, single-phase-shift (SPS) control popularly adopted DAB achieve simple control. Aiming at increasing light load efficiency of high-frequency under SPS control, this letter proposes concept full range zero-voltage-switching ...

A new family of single-switch three-phase highpower-factor rectifiers, which have continuous input and output currents, is introduced. By using a multiresonant scheme, the transistor operates with zero-current switching (ZCS), and the diodes operate with zero-voltage switching (ZVS). These multiresonant rectifiers with a single transistor are capable of drawing a higher quality input-current wa...

In this study, a new Phase Shifted Full Bridge (PSFB) Pulse Width Modulated (PWM) isolated dc-dc converter is proposed. In the proposed converter, resonant inductor is replaced with Linear Variable Inductor (LVI) that is controlled by output current. The soft switching operation range is increased and the dependency of ZVS operation on the load current is decreased. The required energy for ZVS ...
