Abstract

A voltage-compliant power converter module which converts power from an input source for delivery to a load, the load being external to the voltage-compliant converter module and including an external filter capacitance of value Ce for providing ripple filtering of the load voltage delivered to the load, the load being connected to the voltage-compliant converter module via load interconnections external to the voltage-compliant power converter module, the load interconnections being characterized by a total parasitic load inductance of value L1. The converter module includes input terminations for connection to the input source and output terminations for connection to the load interconnections. Switching power conversion circuitry is connected to receive input power via the input terminations from the input source, the power conversion circuitry including one or more switching devices, the switching devices delivering a pulsating voltage waveform at switching frequencies within a nominal operating range. Power delivery circuitry receives the pulsating voltage waveform from the switching power conversion circuitry and delivers power to the load via the output terminations and the load interconnections, the power delivery circuitry including an output capacitor, of value Co, and output inductor, of value Lo, and output interconnections between the output capacitor and the output terminations, the output interconnections and the output terminations being characterized by a total parasitic output inductance of value Lp. The output inductor, the external filter capacitor, the output capacitor, the parasitic load inductance, and the parasitic output inductance defining a first breakpoint frequency, f1, which is lower than the lowest switching frequency in the nominal operating range.
