Journal ArticleDOI
A noncontact charger using a resonant converter with parallel capacitor of the secondary coil
TL;DR: In this article, a noncontact charging system using a resonant converter is presented, where the power transfer ability of a detachable transformer is improved by using a parallel capacitor connected to the secondary coil.
Journal ArticleDOI
A new method to regulate resonant converters
Wen-Jian Gu,Koosuke Harada +1 more
TL;DR: In this article, a new family of resonant converters that are regulated at a fixed switching frequency is proposed, and a steady-state analysis of the Class E resonant converter regulated by a switch-controlled capacitor is presented.
Journal ArticleDOI
The Cascade Connection of Switching Regulators
Hirofumi Matsuo,Koosuke Harada +1 more
TL;DR: In this article, a cascade connection of switching regulators is introduced which is useful for lowvoltage power supplies, and a new method is proposed for isolating the supply and the load circuit.
Journal ArticleDOI
Phase-controlled DC-AC converter with high-frequency switching
TL;DR: In this article, an analysis of the phase-controlled DC-AC converter is presented, where a pair of switches in each side of the primary and the secondary of the isolation transformer are controlled by the phase difference between the two switches.
Journal ArticleDOI
Analysis and optimization of a nondissipative LC turn-off snubber
TL;DR: In this article, a nonissipative LC turn-off snubber is used to reduce the voltage stress on a switching transistor, which is caused by the energy stored in the transformer leakage inductance.
