A new soft-switching boost converter is proposed in this paper. The conventional boost converter generates switching losses at turn on and off, and this causes a reduction in the whole system's efficiency. The proposed boost converter utilizes a soft-switching method using an auxiliary circuit with a resonant inductor and capacitor, auxiliary switch, and diodes. Therefore, the proposed soft-switching...
This paper presents a class D series resonant inverter with a series capacitor and an auxiliary switch. A capacitor and a switch connected in parallel are added to the series resonant circuit in series, which regulates the output power without frequency modulation. The entire impedance is changed by the difference between the switching frequency and the two resonant frequencies. While the auxiliary...
This work presents a novel battery charger with a zero-voltage-transition (ZVT) pulse-width-modulated (PWM) boost converter that decreases switching losses and attains high charging efficiency. The main switch in the proposed battery charger is conducted under zero voltage and the boost diode is cut off under zero current. Switching is completed under the resonance condition. The proposed battery...
