<p>The present invention provides a circuit for detecting if a load being supplied with a high frequency AC power source is asymmetrical. The input voltage and the DC blocking voltage are connected to a differential amplifier circuit, and any difference in voltage is signaled. The load voltage and the DC blocking voltage are each reduced, for example to 10% and 20% respectively, while keeping them proportional to their respective full values.</p> |
