Abstract

PURPOSE:To suppress the output voltage of a generator under warming-up operation, by a method wherein a spurious signal, which makes the output voltage of the generator higher than an actual value, is superposed on a feedback signal during a period until a temperature sensor detects a predetermined warming-up condition. CONSTITUTION:Before starting, a temperature sensor 3 is made ON. When an operation command switch 2 is closed under this condition, a starter motor is driven and the warming-up operation of an engine is started. The coil 5a of a relay 5 is conducted during the warming-up operation of the engine, therefore, a contact 5b is opened and a voltage signal for cutting a field current If is outputted from a DC-DC converter 6 into an automatic voltage regulator 12. When the temperature sensor 3 detects the predetermined warming-up condition and is put OFF, the conduction of the relay 5 is stopped and the automatic voltage regulator 12 performs a normal operation.

Next, the operation will be explained. Normally, at the start 1t1, the temperature sensor 3 is turned on. When a driving command is output in this state, the switch 2 is automatically closed, the auto choke solenoid 4 is energized, and at the same time, the starter motor is driven and warm-up operation of the engine is started. At this time, the starter motor is repeatedly driven by the timer until the engine reaches a predetermined rotation speed. During warm-up of the engine, the coil 5a of the relay 5 is energized, so the contact 5b is open, and the AVRI 2
km is the field current from the DC-DC converter 6! A voltage (IR 43-) is output that cuts .
The AVRI 2 then performs normal operation and begins supplying power to the load. That is, the field m current (I f) obtained by rectifying and smoothing the alternating current generated in the excitation coil 8
is applied to the field coil 9, and AC power is supplied from the output coil IO to the load. At this time, if the output voltage is below a predetermined voltage, transistor Q+ is off and transistor Q2 is on, and by switching on and off as appropriate according to voltage fluctuations, the field is maintained so that the output voltage is approximately constant. The magnetic current IF is controlled, but when the output voltage becomes too high, a feedback signal obtained by rectifying the induced voltage of the detection coil 11 causes the transistor Q to remain on and the transistor Q2 to continue to be off. Field current in field coil 9! ``There will be almost no supply.
