摘要: This paper addresses the problem of small-signal modeling digitally controlled dc-dc series resonant converters when using a combination phase shift and pulse width modulation. Examples such combined modulation techniques have been recently proposed as part online efficiency optimization controllers, in which regulator acts on both between input output legs duty cycle one converter legs. extends dynamic phasor approach, employed for instance pure control is used, to more general multi-harmonic model accounts effects baseband components switching frequency components. Theoretical findings confirm need an extended order fully capture dynamics. Simulations experimental results are presented validate approach.
