The hybrid cascaded nine-level inverter can output more levels using fewer H-bridge units. Under the mixed carrier cascaded modulation strategy, the quality of output voltage waveform is higher, but the output power is not balanced, which will lead to uneven heating and shorten the service life of the equipment. Under the mixed carrier phase-shift modulation strategy, the power self-balancing can be completed, but the power balancing time is too long. Aimed at these problems, a novel hybrid modulation strategy is proposed, where the high-voltage unit is modulated by a stepped wave and voltage constraints are added, and the carrier wave of the low-voltage unit is reconstructed. Compared with the traditional modulation strategy, this strategy can achieve the power balance of three units in the full modulation regime after adding voltage constraints, and reduce the time required for the power balance of the low-voltage unit. Simulation and experimental results verified the feasibility of the proposed modulation strategy.
