ABSTRACT:
A switching circuit for an inductive load such as a switched reluctance machine comprises two separate switching circuits for separate portions of the inductive load. A supply voltage is applied across the two circuits which are connected together at a node between two dc link capacitors. Each separate circuit is exposed to only approximately half the supply voltage between a respective terminal and the central node so that conventional switching components can be used to handle higher voltages applied across the two connected circuits.
