DC to polyphase inverter utilizing a plurality of switching device and a transformer having a plurality of primary and feedback windings connected in circuit with the switching device

摘要

A DC to polyphase inverter is disclosed having a transformer with a plurality of primary and secondary windings. The DC input voltage is applied to each of the primary windings of the transformer. Each primary winding is connected in circuit with a switch. Each of the switches are operated such that the conduction time of each switch is related to the conduction time of each other switch in a predetermined fashion. The secondary windings are arranged to provide a polyphase output signal, that is, a plurality of output signals bearing a specified phase relationship one to another.
