This paper presents a boost converter with the maximum power point tracking (MPPT) technique for thermoelectric energy harvesting (EH) applications. The technique realizes variation tolerance by adjusting the switching frequency fSW of the converter. A finely controlled zero-current switching (ZCS) scheme together with the accurate MPPT technique enhances the overall efficiency (η) of the converter because of an optimal turn-on ...

The trend in power converters is towards increasing power densities. In order to achieve this goal, it is necessary to reduce power losses, overall system size and weight by increasing the switching frequency. High reliability is also very important for todaypsilas switched mode power supplies. The zero- voltage-switching (ZVS) or zero-current-switching (ZCS) topologies that allow for high frequency switching while ...

This paper presents a novel isolated single stage buck-boost inverter for implementing dc-to-ac, ac-to-dc or dc-to-dc. The BBI has better performances, in terms of low cost, high efficiency and high voltage gain. Through the HEV/EV application, the circuit operation principles and characteristics have been analyzed. And then, a novel Synchro-Switching SVPWM have been presented to obtain the maximum buck-boost factor ...

A new zero-voltage and zero-current-switching (ZVZCS) full-bridge (FB) pulse width modulation (PWM) power converter is proposed to improve the performance of the previously presented ZVZCS FB PWM power converters. By adding a secondary active clamp and controlling the clamp switch moderately, ZVS (for leading-leg switches) and ZCS (for lagging-leg switches) are achieved without adding any lossy components or the saturable ...

A new single-phase high power factor rectifier is proposed, which features regulation by conventional pulsewidth modulation (PWM), soft commutation, and instantaneous average line current control. A new zero-current-switching PWM (ZCS-PWM) auxiliary circuit is configured in the presented ZCS-PWM rectifier to perform ZCS in the switches and zero-voltage-switching (ZVS) in the diodes. Furthermore, soft commutation of the main switch is achieved ...
