Abstract :
Employing the transformer leakage inductance, one cross-coupled capacitor, one clamped diode and two switches, an advanced Integrated Filter Converter (IFC) with two-switch forward configuration is proposed. By adding two extra diodes, it provides a comprehensive solution to perform core-reset, input filter, voltage-clamped and voltage-sharing functions. Consequently, non-pulsating input current, low voltage stress and high efficiency performance can be achieved. In this paper, the circuit operation is illustrated by PSpice simulation waveforms, and an experimental circuit of a 100 kHz, 10V/20A is described.
