<p>PURPOSE:To prevent the short circuit and the like of an apparatus surely, by forcibly grounding the input signal of the main transistor of an inverter apparatus through linking the input signal to the OFF state of the control power switch of a control power circuit. CONSTITUTION:A generator apparatus 1 is composed of a generator 2 and an inverter apparatus 3, and said generator 2 has the stator coil 4 of series- connected first and second coils 4a and 4b to charge a battery 6 with DC via rectifier circuit 5. On the other hand, the inverter apparatus 3 consists of an output rectifier circuit 7 for the second coil 4b, an inverter circuit 8 composed of four main transistors Tr1 to Tr4, a control power circuit 9 for the inverter circuit, a control signal generator circuit 10, a drive circuit 11 and others, and said control power circuit 9 is provided with a control power switch SW. Thus, when the switch SW is turned ON, a pulse signal with a specified period from the control signal generator circuit 10 is supplied to the drive circuit 11, and when the switch is turned OFF, the output of the generator circuit 10 is grounded forcibly.</p> |
