Adaptive zero voltage switching (zvs) loss detection for power converters

A device comprising:

• a zero voltage switching (ZVS) circuit that generates a hard switching signal, wherein the hard switching signal includes a false signal and a spike signal;
• a sensor coupled to the ZVS circuit, wherein the sensor detects the false signal and the spike signal;
• a digital to analog converter (DAC) [that supplies a reference signal;
• a comparator coupled to the sensor and the DAC, wherein the comparator uses the reference signal to generate digital pulse signals corresponding to the false signal and the spike signal;
• a blanking component that filters the generated digital pulse signal that corresponds to the false signal;
• a CPU that adjusts timing of a pulse width modulation (PWM) switching cycle based on a detected presence of the spike signal.

A method of detecting a zero voltage switching (ZVS) loss in a power converter, the method comprising:

• detecting by a sensor of a ZVS circuit output that includes a hard switching signal, wherein the hard switching signal includes a false signal and a spike signal;
• generating of digital pulse signals by a comparator, wherein the digital pulse signals correspond to the false signal and the spike signal;
• filtering by a blanking component of the generated digital pulse signal that corresponds to the false signal;
• adjusting by a central processing unit (CPU) of a timing of a pulse width modulation (PWM) switching cycle based on a detected presence of the spike signal.
