Abstract:
A rectifier circuit, comprising:a transformer having a primary winding and a secondary winding;a first rectifying element having a first terminal connected to a first end of the secondary winding of the transformer and a second terminal connected to a reference voltage;a second rectifying element having a first terminal connected to a second end of the secondary winding of the transformer and a second terminal connected to the reference voltage, the first and second rectifying elements rectifying a voltage provided to the primary winding of the transformer;a first voltage clamping element having a first terminal connected to the first end of the secondary winding of the transformer and a second terminal;a second voltage clamping element having a first terminal connected to the second end of the secondary winding of the transformer and a second terminal;a first capacitive element having a first terminal coupled to the second terminal of the first and second voltage clamping elements, the first capacitive element cooperates with the first and second voltage clamping elements to collect energy appearing at the first and second ends of the secondary winding of the transformer so that a voltage appearing on each of the first and second ends of the secondary winding is clamped to a maximum voltage approximately equaling a voltage appearing across the first capacitive element;an inductive element having a first end connected to the secondary winding and a second end comprising an output terminal of the rectifier circuit; anda second capacitive element having a first terminal connected to the second end of the inductive element and a second terminal connected to the reference voltage.
