Abstract

A single-phase induction motor is driven in a conventional half bridge configuration with its run winding connected between the junction of two alternately operated power switching transistors in series and the junction of two series capacitors. The run winding is split into two halves connectible in parallel across the bridge for normal running and connectible in series to provide a direct current path for braking current, bypassing the capacitors. A switch is provided to control the connection of the two half windings.
