<p>PURPOSE:To utilize a half-wave output effectively by supplying a negative half- wave output being not fed to the battery charging of a charging generation coil to an AC load while the half-wave output is short-circuit controlled with a triac according to an AC voltage. CONSTITUTION:A rectifier 7 is provided between a generation coil 1 for charging a battery 3 and a generation coil 2 for driving an AC lead 4 and a triac 6 is connected to the cathode side thereof as controlled with an AC voltage control circuit 100 and a DC voltage control circuit 200. A negative half-wave output not being fed to the battery charging of the generation coil 1 is fed to a load 4. When an output to be fed to the load 4 increases with an increasing generation output and when the battery voltage exceeds a set value, the triac 6 is short-circuited with the circuits 100 and 200 to bypass excessive output. This always prevent overvoltage of the load 4 and overcharging of the battery 3 thereby extending the life.</p> |
