| 摘要 |
The present invention relates to a push-pull converter using a plurality of switches, which turns a third switch on during a constant period including a time that first and second switches are turned off and overlapped with each other in a current source converter using an inductor in a power side, so as not to allow current to flow in a transformer. According to the present invention, a power loss can be reduced since current does not flow in a transformer during a period that the current does not be transferred to a load, thereby significantly increasing efficiency of the push-pull converter. |
