An inverter topology circuit, an inversion method and an inverter are provided. The inversion method comprises: adding a fifth switching tube (Q5), a sixth switching tube (Q6), a fifth diode (D5), a sixth diode (D6) and a first capacity (C) on the existing inverter circuit including a bridge arm; connecting the fifth switching tube (Q5) in parallel with the fifth diode (D5); connecting the sixth switching tube (Q6) in parallel with the sixth diode (D6); connecting the positive electrode of the fifth diode (D5) with the negative electrode of a direct current source (DC) and connecting the negative electrode thereof with the junction circuit formed by a second inductance (L2) and an alternating current source (AC); connecting the positive electrode of the sixth diode (D6) with the negative electrode of the direct current source (DC) and connecting the negative electrode thereof with the junction circuit formed by a first inductance (L1) and the alternating current source (AC).The inverter topology circuit, inversion method and inverter could prevent the turn-on and turn-off loss of high frequency switches, improving work efficiency and energy efficiency, realizing wide range input voltage, preventing the common-mode leakage current generated by the inverter circuit and therefore improving security. |
