Zero voltage switching for flyback converter

A apparatus for controlling a power converter, the apparatus comprising:

• a controller configured to:
• generate a switch control signal for controlling a switch of the power converter;
• and
• generate a mode control signal that indicates a target operation mode selected from a plurality of operation modes of the power converter;
• a first output terminal configured to output the switch control signal to control the switch;
• and
• a second output terminal configured to transmit the mode control signal via a wireless channel.

An apparatus for controlling a power converter, the apparatus comprising:

• an input terminal configured to receive a mode control signal through a wireless channel, the mode control signal indicating a target operation mode selected from a plurality of operation modes of the power converter;
• a controller configured to, based on the mode control signal:
• determine the target operation mode;
• and
• generate a switch control signal for controlling a switch of the power converter in the target operation mode;
• and
• an output terminal configured to output the switch control signal to control the switch.

A method comprising:

• selecting, by a primary side controller of a power converter, an operation mode from a plurality of operation modes of the power converter;
• generating, by the primary side controller, a mode control signal based on the operation mode;
• transmitting, via a wireless channel, the mode control signal from the primary side controller to a secondary side controller of the power converter;
• generating, by the primary side controller and based on the operation mode, a primary switch control signal to control a primary switch on a primary side of the power converter;
• determining, by the secondary side controller, the operation mode based on the mode control signal;
• and
• generating, by the secondary side controller and based on the operation mode, a rectifier switch control signal to control a rectifier switch on a secondary side of the power converter.
