摘要： A power converter is disclosed. In one aspect, the power converter includes a current sensor configured to sense an inverter current output from an inverter and output a first current having a direct current (DC) component and an alternating current (AC) component. The converter also includes a first circuit configured to extract the AC component, having a preset frequency or a frequency greater than the preset frequency, from the first current and output the extracted AC component as a second current. The converter further includes second circuit electrically connected to the current sensor and the first circuit, wherein the second circuit is configured to output a value substantially proportional to the DC component based on the second current.
