    i am in search of finding a 3 phase inverter circuit ...which converts a dc supply of 12V to 3 phase output waveforms

    found more circuits of transistor pairs 3 in parallel.. but there are no connection to base of transistors ....plzzz any one help for connection of base circuit [​IMG]



    and also if any other type of circuits are available for 3 phase inverter which can drive a 3 phase ac motor......
