    摘要: Systems and methods are provided for delivering energy from an input interface to an output interface. An electrical system includes an input interface, an output interface, an energy conversion module coupled between the input interface and the output interface, and a control module. The control module determines a duty cycle control value for operating the energy conversion module to produce a desired voltage at the output interface. The control module determines an input power error at the input interface and adjusts the duty cycle control value in a manner that is influenced by the input power error, resulting in a compensated duty cycle control value. The control module operates switching elements of the energy conversion module to deliver energy to the output interface with a duty cycle that is influenced by the compensated duty cycle control value.

    摘要: Systems and methods are provided for detecting a resonance on a bus coupled to an inverter module. A method comprises generating a first signal on the bus with a first frequency and sweeping the first signal from the first frequency to a second frequency. A second signal, which may be influenced by a characteristic of a component coupled to the bus, is obtained from the bus during the sweep of the first signal from the first frequency to the second frequency. The method further comprises determining a resonant frequency based on the first signal and the second signal and updating the inverter module such that the resonant frequency is not used as a switching frequency for the inverter module.
