<p>PURPOSE: To provide a voltage controller which shows excellent responsiveness against a frequency variation when the frequency of the AC output of a magnet- type generator is varied in accordance with the revolution of the generator. CONSTITUTION: A reference voltage generating circuit 8 detects a battery voltage and generates a threshold voltage following the variation of the voltage. As the battery voltage is varied depending upon the frequency of the AC output signal of a generator 1, as a result, the threshold voltage corresponding to the frequency variation of the AC output signal of the generator 1 is supplied from the reference voltage generated circuit 8. In a phase controller 7, the threshold voltage is compared with a saw-tooth signal which is the integral output of the generator output and a phase control trigger signal which is determined by the cross point of the threshold voltage and the saw-tooth signal is supplied to a phase control device 2. The time interval until the phase control device is ignited is controlled by the trigger signal and, as a result, a power supplied from the generator to the battery is controlled. With this constitution, the voltage control with excellent responsiveness against the freqency variation of the AC output signal of the generator can be achieved.</p> |
