ABSTRACT:
A power supply system including an inverter, a reserved power source and changeover switches for outputting one of outputs of the inverter and reserved power source to supply a load current to a load. The system further includes a control circuit for controlling a phase, a frequency and a voltage of the output of the inverter to coincide with a phase, a frequency of the output of the reserved power source and a specified voltage, respectively. The specified voltage is determined to be a predetermined reference voltage when the load current is below a detection level and to be a reduction voltage decided between zero volt and the voltage of the reserved power source when the load current is equal to or more than the detection level. A method for controlling a power supply system described above is also disclosed.
