    • Mitigating the DC content of an AC output from an inverter is important for electrical system reliability. The inverter may be powered by unbalanced DC inputs while still mitigating the DC content of the AC output wavefrom. The present invention provides methods to mitigate the DC content in the output DC voltage by reshaping the PWM reference signals (carrier signals) according to the DC content in such a way that the DC content is canceled. These reshaped PWM reference signals may be, for example, unsymmetrical reference waveforms. Unlike conventional methods for providing an AC voltage from a DC voltage with an inverter, which may result in DC content in the output AC voltage when an unbalanced DC input voltage is supplied, the present invention provides methods for mitigating the DC content in an AC voltage, even if the inverter providing the AC voltage is supplied with unbalanced DC voltage.
    • 减轻逆变器交流输出的直流含量对于电气系统的可靠性很重要。 逆变器可能由不平衡的直流输入供电,同时还能缓解交流输出波的直流含量。 本发明提供了通过以DC内容被取消的方式根据DC内容重新整形PWM参考信号(载波信号)来减轻输出DC电压中的DC内容的方法。 这些重构的PWM参考信号可以是例如非对称参考波形。 与用于从逆变器提供来自直流电压的交流电压的常规方法不同,当提供不平衡DC输入电压时,这可能导致输出AC电压中的DC含量,本发明提供了用于减轻AC电压中的DC含量的方法 即使提供交流电压的逆变器供给不均衡的直流电压。
