Abstract
The present invention provides a control circuit with multiple power sources, which accepts an output signal from a comparator circuit. This control circuit with multiple power sources contains two components: one is a voltage transferring circuit, which connects to the comparator and accepts the first and the second input voltages to react the controls of respective output signals for generating the first voltage potential and the second voltage potential; another is an output circuit, which connects to the voltage transferring circuit to react the controls of the first voltage potential and the second voltage potential for deciding the correct output from the first input voltage or the second input voltage.
