Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0015] The invention provides a boost unit converter circuit with an inductance built in to realize high-gain and high-efficiency power conversion. The built-in boost unit of the inductance can realize the increase of the gain, and under the condition that the leakage inductance of the coupling inductor and the resonance period of the energy storage capacitor must be less than the conduction time of the power switch tube, it can realize the zero-current turn-off of the freewheeling diode to improve the conversion efficiency.
[0016] Such as figure 1 The converter with a built-in inductance step-up unit shown includes a built-in inductance step-up unit, a DC voltage source V in , power switch tube S1, output diode D o , filter capacitor C O and load R L , characterized in that: the DC voltage source V in It is connected with the input end o...
