Uses two three-phase full-bridges (totaling six legs) driven with 180° phase-shifted PWM, combined with SiC devices' high-speed switching, to achieve ripple current cancellation, doubled power capability, and high-efficiency operation.

The three-phase six-leg SiC interleaved parallel motor drive achieves effective ripple current cancellation** (equivalent switching frequency doubling), increased power capability, and significant optimization of system efficiency and power density through its phase-shifted dual-inverter parallel** structure leveraging the high-speed, low-loss characteristics of SiC devices. It is an advanced solution for high-power-density, high-efficiency motor drive applications.
