A system for controlling a power signal for zero voltage switching (ZVS) includes a voltage zero crossing detection module to detect a zero voltage condition in response to an inverter voltage from a resonant inverter crossing zero volts, and a current zero crossing detection module to detect a zero current condition in response to an inverter current from the resonant inverter crossing zero amps. The system further includes a phase detect module to detect actual phase data corresponding to an actual phase angle between the inverter voltage and the inverter current based on the zero voltage and zero current condition. The system further includes a comparator to determine a phase difference between a desired phase between the inverter voltage and the inverter current and the actual phase angle. The system further includes a controller to adjust a property of a resonant inverter to reduce the phase difference.
