PWM Inverter output filter: cost-losses trade off and optimal design

Résumé

This paper describes how to design the output filter of a PWM inverter used in a Uninterruptible Power Supply. Several constraints apply to this design: physical limitations of all material and components, output waveform quality, losses, cost, ... All models used in the design process are described: semiconductor, inductor and capacitor losses, cost, Total Harmonic Distortion (THD), short circuit behavior... Input parameters are control law, switching frequency, inductor design parameters (number of turns and magnetic circuit) and capacitor values. Based on these design models, optimization is carried out, and cost-losses trade-off curves are deduced. Two power levels (30kVA and 300kVA) are taken as design example, with the same models, in order to show the robustness of the method.
