POWER UNIT AND VOLTAGE TRANSFORMER |
摘要 |
A power supply apparatus 200 comprises an energy supplying circuit 210 for supplying energy at a predetermined timing, and an energy preserving circuit 220 for receiving the energy supplied from the energy supplying circuit 210 and preserving the energy. The energy preserving circuit 220 includes an inductor 221, a capacitance 223 connected to one end of the inductor 221 at a node 222, and a capacitance 225 connected to the other end of the inductor 221 at a node 224. Energy is supplied to a load via at least one of the node 222 and the node 224. <IMAGE> |
