The present invention relates to a diode clamping dual-flyback inverter, which comprises a first flyback circuit and a second flyback circuit. The first flyback circuit and the second flyback circuit operate according to the subareas of the coordinates of output current and voltage, so as to realize the inverted output. The diode clamping dual-flyback inverter has the following advantages: the single-stage structure realizes the step-up inverted output, which reduces the size, weight and cost of the whole machine; the high-frequency electric isolation is realized; the whole circuit has fewer active-power devices; the circuit has a simple structure and low expense; the control proposal is simple and can be easily realized; the original polygonal voltage of the transformer is clamped withina certain range, which effectively inhabits the voltage peak of switches.
