PROJECT TITLE :

Zero-current switching method for dc–dc buck converter in portable application

ABSTRACT:

A unique zero-current switching (ZCS) method for dc–dc buck converter is proposed. Rather than a standard high precision and high speed comparator, a comparator with adaptive offset is meant here. By detecting the conduction of parasitic body diode once low-aspect power transistor turned off, the offset is automatically adjusted to achieve ZCS. Therefore the delay and offset of comparator are no longer an obstacle in circuit design and therefore the measurement results show that the turned-off inductor current is <10 mA, onep.c of the peak value of inductor current and its power consumption is no larger than traditional ones.
