Abstract
A MOSFET control circuit for use in generators with dual windings. The MOSFET switch consists of two or more MOSFETs connected between the upper and lower windings of a three-phase generator to permit the windings to operate in series or in parallel. The gate of one of the MOSFETs is controlled by a gate drive circuit that turns the MOSFET ON when the windings are to operate in series. The MOSFET is OFF when the windings are to operate in parallel.
