Patent ID: 8374004

Claim:
An isolated alternating current (AC)-direct current (DC) converter, comprising: a slave control circuit that includes: a first transistor configured to connect to a primary side inductor of a transformer; and a slave driver module configured to, based on receiving a command, control switching of the first transistor; a master control circuit that includes: a first diode having an input connected to a first end of a secondary side inductor of the transformer; a capacitor having a first end and a second end, wherein the first end of the capacitor is connected to (i) an output of the first diode and (ii) a load, and wherein the second end of the capacitor is connected to a second end of the secondary side inductor; and a master control module configured to sense a feedback voltage across the load, and generate the command based on (i) the feedback voltage and (ii) a reference voltage; and a coupler configured to communicate the command from the master control module to the slave driver module, and provide isolation between the master control module and the slave driver module.
