摘要：
This paper presents a reduced-switch motor drive system, which is made up of a single-phase half-bridge rectifier circuit, ripple power decoupling unit, three-phase inverter circuit, and three-phase motor. Due to the ripple power decoupling unit, the DC-bus of drive system could also provide DC power supply for other DC loads. The ripple power decoupling unit almost shares all components with rectifier and inverter circuit, so this is a low-cost solution. Considering the strong coupling of all kind of components in the system, a hybrid model predictive control (MPC) is introduced to coordinate the operation of the decoupling circuit, rectifier, and inverter circuits. The effectiveness of this scheme is verified with the experimental results.
