A Bilateral Zero-Voltage Switching Bidirectional DC-DC Converter with Low Switching Noise
This paper proposes a novel bilateral zero-voltage switching (ZVS) bidirectional converter with synchronous rectification. By controlling the direction and timing of excessive current injection, the main power switches can achieve bilateral ZVS under ...

Accurate Measurement of Dynamic on-State Resistances of GaN Devices under Reverse and Forward Conduction in High Frequency Power Converter [PDF]
Because of trapped charges in GaN transistor structure, device dynamic ON-state resistance RDSon is increased when it is operated in high frequency switched power converters, in which device is possibly operated by zero voltage switching (ZVS) to reduce ...

The arm‐multiplexing modular multilevel converter (AM‐MMC) is a lightweight, high‐power‐density topology whose conventional modulation strategies require large circulating currents to maintain energy balance. This paper establishes a time‐domain analytical model of the AM‐MMC energy‐balance mechanism and proposes an optimised independent arm modulation

Analytical calculation of resonant inductance for zero voltage switching in phase-shifted full-bridge converters [PDF]
The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the ...

Method to Maximise Utilisation Rate of Flux Linkage in Coreless Transformer
A coreless transformer (CLT) with a maximum utilisation rate of flux linkage is proposed. Compared to existing CLTs, the proposed CLT operates at a significantly lower frequency of 100 kHz, and there is no need for superconductors. Compared with the magnetic‐core transformer (MCT), the proposed CLT has almost the same efficiency, while the gravimetric ...
