Title:
POWER CONVERTER CONTROL CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/141899
Kind Code:
A1
Abstract:
A control circuit for a power converter. The power converter comprises a primary circuit for receiving a supply power, with the primary circuit having a primary connection. A secondary circuit provides a load power to a load. The secondary circuit has a secondary connection connected to the primary connection. There is a current sensing circuit for detecting a current sense signal derived from an output current, and a voltage sensing circuit for detecting a voltage sense signal derived from an output voltage. The control circuit comprises a controller for controlling one or more switches in the primary circuit to control the output current and/or the output voltage in accordance with one or more control profiles and based on the current sense signal and/or the voltage sense signal.
