PROBLEM TO BE SOLVED: To provide an excellent power supply which can effectively utilize the power of main power source such as an AC power source, DC power source, etc., and the power generated by a generation means with simple constitution, and has a long life. SOLUTION: This is a power supply S which performs power supply to a load L from both of the main power source 1 of AC and the auxiliary Dc power source 3 provided in parallel with the main power source 1, and the main power source 1 and the load L are connected with each other through an output conversion means 10 which converts the AC output of the main power source 1 into DC output, and also the auxiliary DC power source 3 and the load L are connected with each other through a booster means 11 which controls it into voltage higher than the output voltage from the output conversion means 10. |
