An automatic controller to control the AC load, the automatic controller comprises a control winding solid dominant isolation L - 4 of the (1) and (2) includes a high frequency rectifier circuit, voltage regulator circuit (3), micro power circuit (4) circuit system composed of load resistance R. Isolation of control winding L 4 provides power to the circuit, the circuit system by connecting the micro power circuit (4) impedance level changes the load resistance R and the output terminal of the P between the P and the output end of the circuit to change the system, so as to realize the control of solid state dominant automatic controller (1) Z L feed to AC load. It is used to manufacture high performance fully integrated solid state automatic controller with various isolated functions.
