PROBLEM TO BE SOLVED: To adequately supply power to the load. SOLUTION: This power supply system is provided with an auxiliary transformer 2 connected in series to the output of a circuit breaker 1, and a second inverter for varying the applied voltage to this auxiliary transformer 2. When the power to the load is saved, the ON/OFF operation of the second inverter 11 is controlled with a control apparatus 10 to impress the first voltage to the auxiliary transformer 2. When the voltage of the power to the load is compensated, the ON/OFF operation of the second inverter 11 is controlled with the control apparatus 10, and the second voltage reflecting the phase of the first voltage is applied to the auxiliary transformer 2. |
