ABSTRACT:
A simplified, small-sized RV generator has a power source with a voltage adjusting circuit. The adjusting circuit includes a plurality of polysilicon resistors connected serially with polysilicon fuses connected in parallel with and to both ends of each of the resistors. A resistor network is connected to the voltage adjusting circuit and composed of a plurality of polysilicon resistors for providing a reference voltage, based on the output voltage of the adjusting circuit.
