<p>Systems and methods of controlling an uninterruptible power supply are provided. The uninterruptible power supply includes an input configured to receive input power an output a power conversion circuit coupled with the input and the output and a controller coupled with the power conversion circuit. The power conversion circuit includes an inverter which includes a low pass filter. The low pass filter includes an inductor and the controller is configured to provide control signals to the inverter such that a first current measured at the inductor generates a second current measured at the output where the first current has a first polarity and the second current having a second polarity and the first polarity is either zero or the same polarity as the second polarity.</p> |
