Chlorinator synchronous rectification

A method comprising:

• establishing an electrical coupling between an alternating current mains power source and a chlorinator system of a salt water pool and spa system, wherein the electrical coupling comprises a transformer electrically coupled between the alternating current mains power source and a synchronous rectifier, wherein the transformer is configured to electrically isolate control electronics of the chlorinator system from the alternating current mains power source prior to rectification by the synchronous rectifier;
• synchronously rectifying the alternating current mains power source using the synchronous rectifier of the chlorinator system to generate a direct current power source, wherein the synchronous rectifier comprises:
• an output-voltage feedback;
• and
• a controller configured to control the direct current power source generated by the synchronous rectifier using the output-voltage feedback;
• stepping down a voltage of the alternating current mains power source or the direct current power source;
• and
• providing the direct current power source at a stepped down voltage to electronics of the chlorinator system, wherein the electronics of the chlorinator system comprise:
• an electrolysis cell configured to receive a flow of pool water and to electrolyze sodium chloride in the pool water to generate chlorine;
• and
• the control electronics configured to control operations of the chlorinator.

A pool or spa system, comprising:

• a chlorinator system comprising:
• a swimming pool chlorinator configured to perform chlorination operations of a salt water pool system;
• at least one transceiver configured to provide short-range communication between the swimming pool chlorinator and at least one additional component of the salt water pool and spa system;
• a power source coupler configured to receive alternating current power from an alternating current power source;
• and
• a synchronous rectifier configured to convert the alternating current power to generate a direct current power source to provide power to the swimming pool chlorinator and the at least one transceiver, wherein the synchronous rectifier comprises:
• an output-voltage feedback;
• and
• a controller configured to control the direct current power source generated by the synchronous rectifier using the output-voltage feedback;
• and
• a transformer electrically coupled between the power source coupler and the synchronous rectifier, wherein the transformer is configured to electrically isolate control electronics of the swimming pool chlorinator from the alternating current power source prior to rectification by the synchronous rectifier.
