Abstract
A controlling method of a converter includes performing a state detecting step and a switch controlling step. The state detecting step is performed to detect an operation state of a secondary side rectifier of the converter from a control winding. The switch controlling step is performed to control an active clamp switch of the converter according to the operation state of the secondary side rectifier. The secondary side rectifier is a diode.
Claims24
A controlling method of a converter, comprising:
- performing a state detecting step to detect an operation state of a secondary side rectifier of the converter from a control winding;
- and
- performing a switch controlling step to control an active clamp switch of the converter according to the operation state of the secondary side rectifier;
- wherein the secondary side rectifier is a diode.
A controlling method of a converter, comprising:
- providing an active clamp switch and a control winding in a primary side circuit and providing a secondary side rectifier in a secondary side circuit;
- performing a state detecting step to detect an operation state of the secondary side rectifier of the converter from the control winding;
- and
- performing a switch controlling step to control the active clamp switch of the converter according to the operation state of the secondary side rectifier;
- wherein the secondary side rectifier is a diode.
A converter including an active clamp switch and a secondary side rectifier, comprising:
- a primary side circuit, wherein the primary side circuit comprises the active clamp switch and a control winding;
- and
- a secondary side circuit, wherein the secondary side circuit comprises the secondary side rectifier having an operation state;
- wherein the operation state of the secondary side rectifier of the secondary side circuit is detected from the control winding to control the active clamp switch of the primary side circuit, and the secondary side rectifier is a diode.
