摘要： A first primary winding N11 of a transformer 1 is connected with a commercial power source 30 via a transistor Q1, and a second primary winding N22 of the transformer 1 is connected with a backup battery 31 via a transistor Q2. An electric power on the second primary winding N12 is output for a controlling apparatus. When a voltage of the commercial power source 30 is larger than a predetermined value, a backup stopping circuit 10 turns off a LED 9 and stops the transistor Q2. The second primary winding N22 is connected with input terminals 14, 15 as a power source for charging a battery 31. While the transistor Q2 is stopped, an electric power for the battery is output from the second primary winding N22. Since the LED 9 turns on at the time of electric power breakdown, the electric power for the battery is stopped.

摘要： In a co-generated power supply system for performing dispersed power supply to a load, a wind turbine generator, a solar cell and a fuel cell whose rated voltages are made equal to a rated voltage of a storage battery are used as DC power sources. These DC power sources, a commercial AC power source and the load are connected to each other via a bi-directional electronic transformer. Thus, the co-generated power supply system, in which the electric power of a natural energy system having many fluctuation factors is combined with stable electric power such as a load leveling battery or a fuel cell, allows the stable electric power to be supplied to the load via the electronic transformer commonly, thereby reducing the cost and enhancing the performance of the entire system.

摘要： It is an object of the present invention to provide an uninterruptible switching regulator with which smaller size and lower cost can be achieved while the power supply efficiency is raised, which is accomplished by the effective utilization of an RCC type switching circuit. When the commercial AC input power supply 1 is operating normally, the AC-side RCC type switching circuit 21 is operated preferentially to supply power to the secondary drive circuit 25, but when there is a power outage with the commercial AC power supply 1, the DC-side RCC type switching circuit 69 is operated to supply power to the secondary drive circuit 25, and these two switching circuits can be switched at high speed.
