Abstract：
 A voltage slump and surge dynamic compensator characterizes that a test and control circuit with a mciroprocessor as its core enables the sinusoidal voltage output by an inverter to be directly connected in series with the power supply voltage during slumps and surges to compensate the necessary voltage and not influence the load voltage. It utilizes the voltage left by the system in slump and adds it to the output voltage of the inverter so the load gets a stable operating voltage and it crossly charges the DC capacitor for half period.
