<p>PURPOSE:To make it possible to generate an external power supply in either case of running and stopping of an automobile by controlling the magnetic field of a power generator on the basis of an inverter load current detection signal and signals of detected voltage and frequency of the power generator. CONSTITUTION:Electric power generated by a generator 3 is supplied to an inverter unit 4 to be used as an external power supply by means of a socket 19 and a signal from an electric current sensor 6 installed between the generator 3 and the inverter unit 4 is supplied to a controller unit 7 as a load current detection signal of the inverter unit 4. Also, signals of detected voltage and frequency from the generator 3 are supplied to the controller unit 7. The controller unit 7 controls the magnetic field of the generator 3 on the basis of each detected signal. Thus, the generator 3 starts its power generation and the generated power is stored in batteries or used as an external power supply. Accordingly, two power supplies with excellent quality having stabilized frequency can be obtained regardless of the input speed of the generator 3 even though the automobile is in any condition.</p> |
