This paper presents a novel application of half-bridge series-parallel resonant converter (HBSPRC) for dc source and secondary battery interface. The converter practically eliminates both low- and high-frequency current ripple on the battery, thus maximizing battery life without penalizing the volume of the charger circuit. Moreover, operation above resonance is preferred, because the power switches...
In this paper, different kinds of driving methods for synchronous rectifier (SR) are compared, and a self-biased current driven circuit for SR is proposed. The circuit uses a current transformer (CT) to generate driving signal, as well as provide the driving power. With a capacitor to produce bias voltage, this circuit can be used without considering the location of SR and the output voltage of converter...
This paper presents a high efficiency current-mode DC-DC step-down converter with wide range of output current. The converter adaptively operates as Pulse-Width Modulation (PWM). An on-chip current sensing technique is employed to reduce external components and no extra I/O pins are needed for the current-mode controller. A soft-start operation is designed to eliminate the excess large current during...
