Abstract
(EN)
The present application provides a drive control circuit and a home appliance. The drive control circuit comprises: a half-bridge circuit configured to perform conversion processing on a power supply signal, and specifically comprising a transistor provided with a control terminal; and a filter module configured to filter out an electromagnetic interference signal generated by the transistor, and connected to a conducting line of the half-bridge circuit. The technical solution of the present application helps reduce the electromagnetic interference signals generated by transistors during high-frequency switching, thus improving the accuracy of circuit sampling signals and the reliability of the control process.
