The invention relates to a dual-drive system special for a hybrid power gearbox. The dual-drive system comprises a current stabilizer, a high-frequency inversion assembly, a boosting inductive body assembly, a DC/DC converter and an alternating current output assembly which are installed in an upper cavity of a middle shell, and a control unit installed in a lower cavity of the middle shell. The high-frequency inversion assembly comprises a capacitive body, and the capacitive body is provided with a boost capacitive body, an inversion capacitive body, a group of leakage capacitors connected with the boost capacitive body in parallel, and two groups of leakage capacitors connected with the inversion capacitive body in parallel. Four high-permeability devices in the current stabilizer, four leakage capacitors and two groups of leakage capacitors which are integrated in a capacitive body and are connected in parallel with an inversion capacitive body form a CLCLC filtering configuration. Cooling water channels are laid in the DCDC arrangement area, the inductor arrangement area and the thin-film capacitor arrangement area of the middle shell. Compared with the prior art, the boost circuit is introduced, the working efficiency is improved, the EMC is high, the heat dissipation effect is good, and compatibility is achieved.
