HYBRID SYSTEM, HYBRID SYSTEM CONTROLLING METHOD AND COMPUTER READABLE RECORDING MEDIUM IN WHICH PROGRAM IS RECORDED FOR TO CONTROL THE HYBRID SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a hybrid system capable of charging with a simple and low-cost capacitor provided at the input side of an inverter that drives a driving motor on cranking a hybrid car. PSOLUTION: In a hybrid system 100, when cranking the hybrid car, a starter 23 starts the engine 22, which rotates the motor 21, which then generates electric power. A controller 30 receives an output voltage V1 of a DC power source 10 and a voltage V2 between both terminals of a capacitor 12 with voltage sensors 11, 13 respectively, and, when a difference between the voltage V1 and the voltage V2 is larger than prescribed, controls the inverter 14 in such a way as to charge the capacitor 12 with the electric power generated by the driving motor 21. When the difference between the voltage V1 and the voltage V2 becomes smaller than prescribed, the controller 30 turns on a system relay 20. PCOPYRIGHT: (C)2004,JPO
