ABSTRACT:
A transistorized invertor which is for inverting d.c. to one or more phases of a.c. and in which for the or each phase to be produced there is provided a current transformer primary in an output line of the invertor with the secondary of the current transformer in a base drive circuit for the invertor, the current transformer being effective to feed a proportion of the output current of the invertor back to the base drive circuit in order to provide base drive current for the base drive circuit.
