摘要：The present invention provides a circuit for detecting if a load being suppliedwith a high frequency AC power source is asymmetrical. The input voltage and the DCblocking voltage are connected to a differential amplifier circuit, and any difference involtage is signaled. The load voltage and the DC blocking voltage are each reduced, forexample to 10% and 20% respectively, while keeping them proportional to theirrespective full values.
