摘要（英）：

A single-phase high-gain boost converter is provided with a power supply, a power switch tube, an output capacitor, a first switch capacitor, a second switch capacitor, a first fly-wheel diode, a second fly-wheel diode, a clamping diode, a clamping capacitor, an output diode and a coupling inductor. The coupling inductor comprises a primary winding and a secondary winding. One end of the primary winding is connected with a power supply positive electrode, the other end of the primary winding is connected with the drain electrode of the power switch tube and one end of the first switch capacitor, the cathode of the clamping diode is connected with one end of the clamping capacitor and the anode of the first fly-wheel diode, and the other end of the first switch capacitor is connected with the anode of the second fly-wheel diode and one end of the secondary winding. The other end of the secondary winding is connected with the cathode of the first fly-wheel diode and one end of the second switch capacitor. The other end of the second switch capacitor is connected with the cathode of the second fly-wheel diode and the anode of the output diode. The cathode of the output diode is connected with one end of the output capacitor. The other end of the output capacitor is connected with the negative electrode of the power supply and the source electrode of the power switch tube.
