INITIAL CIRCUITS, FULL BRIDGE SWITCHING CIRCUITS AND HALF BRIDGE SWITCHING CIRCUITS

摘要

An initial circuit is provided. The initial circuit receives a plurality of input signals and controls an initial status of a switching circuit with a plurality of switches. The initial circuit includes a judgment circuit for generating an enable signal according to one of the input signals, and a control circuit for generating a plurality of control signals according to the enable signal and the input signals. The switches are turned off by the control circuit according to the control signals when the switching circuit is in an initial status, and the switches are controlled by the control circuit according to the control signals when the switching circuit is in an operating status.
