    摘要： A compressor monitoring system includes current and voltage monitors, current and voltage averaging modules, a control module, and a switch. The current monitor measures a current drawn by a motor of a compressor. The current averaging module generates first and second average current values based on the current measured by the current monitor. The voltage monitor measures a utility power voltage. The voltage averaging module generates first and second average voltage values based on the voltage measured by the voltage monitor. The control module selectively generates a fault signal when a first ratio is greater than a first predetermined threshold and a second ratio is less than a second predetermined threshold. The first ratio is based on the first and second average current values. The second ratio is based on the first and second average voltage values. The switch deactivates the motor when the fault signal is generated.

    摘要： A power converter includes a DC/DC converting circuit and a first energy storage element. The DC/DC converting circuit includes a first output terminal and a second output terminal. The first energy storage element includes a first terminal and a second terminal. The first output terminal of the DC/DC converting circuit is electrically connected to one terminal of an external load. The first terminal of the first energy storage element is electrically connected to the second output terminal of the DC/DC converting circuit. The second terminal of the first energy storage element is electrically connected to the other terminal of the external load. The DC/DC converting circuit is configured to provide a variable electric power. The power converter provides the power supply according to the DC/DC converting circuit and the first energy storage element, and the variable electric power is less than the power required by the external load.
