Transformerless AC/DC converting control circuit

摘要

The present invention discloses an AC/DC converting control circuit, which is used in transformerless AC/DC converting apparatuses. The control circuit primarily includes a current-switch circuit, a duty-control circuit and a load-current limiting circuit. When electrically connecting with a load and a voltage source in series, the control circuit of the present invention apparently reduces the oscillation during on/off and provides a stable output current. <IMAGE>
