摘要

本文论证了六相多逆变器驱动调制逆变器开关策略混杂的可能性。混合开关方案可用于直流链路电压不等的电力系统的控制。在这种情况下，所提出的逆变器组合PWM技术确保了系统直流电压之间不同比例时相电压的基波谐波的大小相等。混合开关方案与同步PWM算法的结合(用于控制独立逆变器)保证了相电压波形的对称性，这一事实已通过仿真得到证实。

Combined PWM control of multi-inverter installation with two DC-links

Possibility of hybridization of switching strategies for modulated inverters of six-phase multi-inverter drive has been shown in this paper. Hybrid switching schemes can be used for control of power system with unequal voltages of dc-links. In this case the proposed combined PWM techniques of inverters insure equal magnitude of the fundamental harmonics of the phase voltages for different ratios between dc-voltages of system. Combination of hybrid switching scheme with algorithms of synchronous PWM (for control of separate inverters) assures waveform symmetries of the phase voltages, and this fact has been confirmed by simulations.
