摘要： In a power converter apparatus, such as an uninterruptible power supply, aphase reference signal is generated responsive to a DC voltage on a DC bus. A magnitudereference signal may be generated responsive to a phase current of an AC bus and/orthe DC voltage on the DC bus. Power is transferred between the AC and DC bussesresponsive to the phase reference signal and the magnitude reference signal. Generationof the phase reference signal may include generating a DC voltage error signal

responsive to the DC voltage on the DC bus, generating a phase offset signal responsiveto the DC voltage error signal, and generating the phase reference signal responsive tothe phase offset signal. Generation of the magnitude reference signal may includegenerating a volt-amperes reactive (VAR) error signal responsive to the phase currentand generating the magnitude reference signal responsive to the VAR error signal.
