The utility model relates to an elevator electric energy repayment circuit, the in -process of elevator hauler work produce the regeneration electric energy, and in the time of should regenerating electric energy regurgitate to three phase bridge output, catch and the contravariant becomes the alternating current and gives the electric wire netting by three -phase inverter, realizes being incorporated into the power networks, avoids the electric energy extravagant, because the voltage that every switching element of three -phase inverter bore when turn -offing is half the for direct current side voltage only, therefore can reduce and run from opposite directions the requirement of closing the device, reduction switching loss is applicable to high -pressure occasion, add steady voltage electric capacity C1 and the steady voltage electric capacity C2 that the symmetry set up and the appearance value equals through the input at three -phase inverter and realize balanced steady voltage, steady voltage effect preferred, the filtering superior performance, and with the parallelly connected steady voltage electric capacity C1 of equalizing resistance R1, the equalizing resistance R2 steady voltage electric capacity C2 that connects in parallel, the equalizing resistance who equals through two resistances comes balanced electric capacity both ends voltage, force voltage that every steady voltage electric capacity bore only for half of direct current side voltage, thereby it is difficult by the high pressure damage to protect every steady voltage electric capacity.
