Abstract
Capacitors are connected in series between a first DC link section and a second DC link section when the capacitors are charged by a regenerative current derived from an inverter section. During discharge, as first, second switching circuits turn on, the capacitors are discharged with those capacitors connected in parallel between a first DC link section and a second DC link section.
