Abstract

As an alternative solution to powering the new generations of telecommunication and computer systems, high frequency ac distributed power system (HFAC DPS) has potentially high efficiency and excellent transient response. In this paper, HFAC DPS is implemented for a dual output application. An asymmetrical pulse-width-modulated (APWM) resonant inverter and pulse-width-modulated (PWM) series resonant converter are employed as the front-end inverter and on-board load AC voltage regulator modules (AC VRMs) respectively. In the steady-state operation, HFAC DPS can operate in (i) power transfer mode, (ii) no-load mode, and (iii) short-circuit mode. Under the dynamic conditions, HFAC DPS has excellent transient response against the line and load variations. In this paper, simulation and experimental results are presented as the proof-of-concept.
