To meet the growing demand for flexible and reliable power management functions, power conversion using digital signal processing techniques have attracted many attentions recently. In this paper, the design issues about the usage of digital control for switching-type power converter are addressed. Incorporated with the digital processing in the controller, the interface designs on the analog-to-digital...
This paper presents a digital current regulator for an H-bridge PWM converter, having a sampling frequency equal to quadruple of the switching frequency. The current regulator detects the current and manipulates the voltage reference not only at the upper and lower peaks of the PWM triangle carrier but also at its zero crossings. This paper theoretically discusses the switching sequence of the H-bridge...
