Abstract
A power converter comprising an inverter for receiving a supply power and providing an alternating output. An output rectifier receives the alternating output and provides a rectified output to a load. An output winding receives the rectified output, and a sensing winding is inductively coupled to the output winding and provides a sensing output. A controller receives the sensing output and provides a control signal to the inverter for controlling the alternating output. A related method of converting power is also provided.
Claims18
A power converter comprising:
- an inverter for receiving a supply power and providing an alternating output;
- an output rectifier for receiving the alternating output and providing a rectified output to a load;
- an output winding for receiving the rectified output, wherein the output winding connects to the load;
- a sensing winding inductively coupled to the output winding and providing a sensing output, wherein the sensing output is a current sense signal;
- a sensing rectifier to rectify the current sense signal;
- and
- a controller for receiving the current sense signal and providing a control signal to the inverter for controlling the alternating output,
- wherein the inverter comprises two switches, and the controller provides two control signals, each controlling a respective one of the switches.
A method of converting power comprising:
- inverting a supply power based on a control signal to provide an alternating output;
- rectifying the alternating output to provide a rectified output to a load;
- connecting an output winding to the rectified output, wherein the output winding connects to the load;
- inductively coupling a sensing winding to the output winding to provide a sensing output, wherein the sensing output is a current sense signal;
- rectifying the current sense signal;
- and
- providing the control signal based on the current sense signal,
- wherein the supply power is inverted with two switches, and two signals are provided, each controlling a respective one of the switches.
