High-frequency half-wave rectifier system of low-harmonicity and high-efficiency

A high-frequency half-wave rectifier system of low-harmonicity and high-efficiency, which mainly comprises:

• a current output device having an output end and a first flow-return end respectively at both ends for outputting alternating current;
• a rectifying module connected in series with the output end of the current output device for adjusting an output power;
• a resonant tuning unit connected in parallel with the rectifying module for controlling a duty cycle of the rectifying module at a predetermined value;
• a first node located to a side of the first flow-return end farther away from the current output device;
• a voltage regulator module;
• wherein one end of the voltage regulator module is connected in series with the rectifying module and the other end is connected to the first node;
• at least one load element connected in parallel with the voltage regulator module;
• a grounding portion set in one side of the load element;
• at least one flow-return path between the first node and the first flow-return end for guiding a current flown out of the voltage regulator module to the current output device;
• a second flow-return end provided between the output end and the rectifying module;
• a flow-return unit having two ends connected to the first node and the second flow-return end respectively for guiding the current flown out of the voltage regulator module to the rectifying module;
• a resonance module set between the output end and the second flow-return end for reducing Electro Magnetic Interference (EMI) of the high-frequency half-wave rectification system;
• and
• a resistance element set between the first node and the first flow-return end.
