This paper deals with a cost effective IPT wireless EV battery charger which incorporates the simplest quasi-resonant soft switching pulse modulated inverter. In the first place, the operating principle of the single-ended high-frequency resonant inverter linked IPT DC-DC converter treated here is described. This two planar coupling coils type wireless resonant DC-DC converter can efficiently operate...
Harmonic currents generated from the power electric equipment such as IH cooking heaters involve harmful influences to the other equipments connected to the utility grid. As for the IH cooking appliances, adding the PFC converter to the input stage of IH cooking heater is one of the practical solutions to suppress harmonic current influences. In this paper, two operation modes; DCM and CCM for the...
This paper deals with a novel type soft switching PWM power frequency AC-AC converter using bidirectional active switches or high frequency PWM controlled cyclo-conversion circuit, which can directly convert utility frequency AC (UFAC, 50 Hz/60 Hz) power to high frequency AC (HFAC) power ranging more than 20 kHz up to 100 kHz. A novel soft switching PWM prototype of high frequency multi-resonant PWM...
