<p>A frequency domain self-synchronization controller (24) for solid state switches (21) is disclosed. The controller (24) analyzes a measured power signal in the frequency domain to identify a frequency domain firing angle and then converts the frequency domain firing angle to a time-domain firing signal command. The time-domain firing signal command is used to fire selected solid state switches (21) of, for example, a static VAR compensator, precisely when the voltage across the selected solid state switches (21) is at or near zero volts, so that the solid state switches (21) are not damaged.</p> |
