Abstract
Simplifying the controller of hybrid type drive unit. The output of a generator driven by engine is connected directly to a motor 7 through a converter or switching circuit 10 without being charged on any battery. The output of each phase of the generator is inputted to the converter 10. A timing controller 126 controls the conduction phase of a thyristor bridge 101 in the converter 10 so as to adjust the quantity of output power. A synchronous standard for phase control is formed based on output wave of an auxiliary winding 26 of the generator. A voltage detector 124 detects an applied voltage on the motor 7 as a motor rotation speed and the conduction angle is increased or decreased so as to maintain a detected voltage at a target value.
