Synchronous rectifier for variable frequency driving of pool or spa equipment

A variable frequency drive for driving one or more pieces of rotating pool or spa equipment, comprising:

• a synchronous rectifier configured to convert an alternating current (AC) input to a direct current (DC) output, comprising:
• a chipset;
• and
• one or more switching components;
• and
• an inverter, configured to convert the DC output to an AC drive signal at a configured frequency.

A method for driving rotating pool or spa equipment, comprising:

• receiving, by a variable frequency drive configured as part of a pool or spa system, an input AC signal and a command to generate an AC drive signal of a particular frequency;
• outputting, to a synchronous rectifier, the input AC signal;
• generating a DC output comprising switching one or more rectifying elements of the synchronous rectifier using a control circuit;
• smoothing the DC output of the synchronous rectifier using bulk capacitance;
• inverting the smoothed DC output using inverter to generate the AC drive signal;
• and
• providing the AC drive signal to one or more pieces of rotating equipment.
