<p>In a battery voltage adjusting circuit, when an output voltage for a generator terminal output by a single phase alternating current generator has a negative polarity, a control circuit turns a first switch element on when a comparative value, which is an effective value or an average value for a lamp voltage for a lamp terminal, is less than a target voltage. Meanwhile, when the output voltage has a positive polarity, the control circuit turns a third switch element on when the comparative value is less than a threshold voltage, which is lower than the target voltage, and turns on a second switch element when the battery voltage for a battery is less than a prescribed voltage.</p> |
