Electrical inverter with mains and load sides has regulator and modulator and uses standard choke arrays in series or parallel in choke modules

摘要

An inverter with mains and load sides comprises a regulator and modulator (16) and mains side commutator chokes, each comprising a module (28) of standard chokes (32) in series or parallel and a load output filter. Each bridge arm is in parallel with a second arm and modules have saturation detection units (30) linked to pulse width adjusters (32).
