ABSTRACT:
Two field effect transistor device means are utilized in conjunction with a special type of transformer having a low impedance primary winding and a high impedance primary winding to energize a secondary circuit to supply power for operating the electronics. The energy storage means for the field effect transistor device means is kept charged either directly from the line or through a voltage in the primary windings of the special transformer when the load switching field effect transistor device means is conducting.
