High Performance Transient Response of High/Low Pulse Voltage using Two-Phase Interleaved DC-DC Buck Converter under Half Sampling Time Deadbeat Control

Abstract

One-cycle current deadbeat and half-cycle current deadbeat are implemented to a two-phase interleaved DC-DC buck converter. It is confirmed that output voltage driven and outputted by half-cycle current deadbeat is more stable. When the capacitance of LC filter was reduced 3.22µF to 1µF, rise time, step-up duration of 40V to 120V, is shortened to 10.3µs significantly.
