Securing Full-Power-Range Zero-Voltage Switching in Both Steady-State and Transient Operations for a Dual-Active-Bridge-Based Bidirectional Electric Vehicle Charger

IEEE transactions on power electronics, 2020
Dual-active-bridge (DAB) circuit is an excellent candidate for a high-efficiency, high-power density, and bidirectional electric vehicle charger. Unlike resonant circuits employing auxiliary inductors and capacitors, DAB minimizes the usage of passive ...

Zero-voltage-switching multi-resonant three-level converters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper proposes a family of zero-voltage-switching multiresonant three-level converters (ZVS-MR-TLCs), which are derived by adding a ZVS-MR multiresonant network to the TLCs. The arrangement of a multiresonant network results in the absorption of all the major parasitic components in the resonant circuit, including the switch output capacitor ...

20-kW Zero-Voltage-Switching SiC-mosfet Grid Inverter With 300 kHz Switching Frequency

IEEE transactions on power electronics, 2019
Although SiC-mosfet has significant advantages on switching performance over traditional Si-IGBT, the switching loss of SiC-mosfet devices at hard switching rises quickly with the increment in the switching frequency.

Charge control for zero-voltage-switching multiresonant converter

IEEE Transactions on Power Electronics, 1996
The operation of zero-voltage-switching multi-resonant power converters (ZVSMRCs) limits the use of peak current-mode control. The charge control technique is found applicable to ZVSMRCs for improving dynamic performance. Charge control compares the total charge of the switch current to the control voltage to modulate the switching frequency. Since the

A new zero-voltage switching DC/DC boost converter

IEEE Transactions on Aerospace and Electronic Systems, 1993
A pulsewidth-modulated (PWM) zero-voltage-switching quasi-resonant boost converter operating at constant switching frequency is presented. In contrast to the frequency-modulated (FM) zero-voltage-switching quasi-resonant boost converter, this converter possesses better controllability and higher operating performance, and overcomes the instability ...
