ABSTRACT:
A switching drive circuit for soft switching is disclosed. It includes an input circuit to receive an input signal. A first delay circuit generates a first delay time in response to the enable of the input signal. A second delay circuit generates a second delay time in response to the disable of the input signal. A switching signal generator generates switching signals. The pulse width of the high-side switching signal is generated in proportion to the pulse width of the input signal. The high-side switching signal enabled after the first delay time once the input signal is enabled. The low-side switching signal disabled in response to the enable of the input signal. The low-side switching signal is enabled after the second delay time once the high-side switching signal is disabled.
