The practical implementation method
Below in conjunction with accompanying drawing the present invention is further specified.
Embodiment one

In switch periods of single switching tube high-gain converter based on coupling inductance multiplication of voltage unit 2 courses of work are arranged, i.e. switching tube S shutoff and switching tube S open the transfer process of work.
Switching tube S is when turn-offing:
The leakage inductance electric current is through switching capacity Cc, output capacitance Co and output diode Do afterflow, and the voltage of switching tube is by clamping capacitance Cc clamp.Energy begins by coupling inductance and clamping capacitance to load transfer.Meanwhile energy also transmits to multiplication of voltage capacitor C m through coupling inductance.Leakage inductance is with clamping capacitance and multiplication of voltage electric capacity generation resonance, because harmonic period is bigger, the leakage inductance electric current can be thought what linearity descended.
The electric current of clamping capacitance Cc of flowing through drops to zero, and this moment, former limit winding current equaled the secondary winding current.Output diode turn-offs naturally, does not therefore have the output diode reverse-recovery problems.Energy continues to transmit to multiplication of voltage capacitor C m during this stage.
When switching tube S opens again:
Because the leakage inductance electric current suppressed current changing rate, so switching tube zero current turning-on almost.After this leakage inductance electric current begins under input voltage and the effect of multiplication of voltage capacitance voltage sum of converting former limit, to begin to descend.
The voltage of sustained diode r1 drops to zero, and the parasitic capacitance Cs of Dr1 begins the former limit leakage inductance Lk resonance with coupling inductance afterwards, and the voltage of parasitic capacitance Cs rises and the leakage inductance electric current begins to rise.
Voltage on the parasitic capacitance Cs can make sustained diode r2 conducting; The former limit leakage inductance Lk of Cc, Cm and coupling inductance begins resonance afterwards; The energy of multiplication of voltage electric capacity begins to shift to clamping capacitance; Meanwhile, coupling inductance equally is delivered to energy the switching capacity from the input power supply as transformer.And the magnetizing inductance Lm of coupling inductance also begins charging.
Output diode Do and two sustained diode r1 and Dr2 are in anti-state partially.Out-put supply is to magnetizing inductance and leakage inductance charging, and exciting current and leakage inductance electric current are linear to rise.
