Integrated L-L-C-T (Inductor-Inductor-Capacitor-Transformer) technology has been the subject of intensive research over the last few years. Its application to resonant power electronic converters has been reported by many of the previous publications. This paper presents the application of a planar L-L-C-T module to the integration of passive module for a Zero-Voltage-Switched Asymmetrical Half Bridge PWM Converter for application in Distributed Power Systems. Two output transformers, two current doubler inductors, the ZVS resonant inductor and the transformer DC decoupling capacitor are integrated into a single module. The design procedure is discussed and some special considerations of the L-L-C-T module in non-resonant applications are addressed. A 1kW 300V - 400V input, 48V output Asymmetrical Half Bridge PWM Converter (AHBC) employing the L-L-C-T module is constructed. A comparison of the AHBC using the integrated passive module and the same circuit using discrete components is given.
