Abstract
A power converter includes a protection circuit, a controller, and a power conversion circuit. The protection circuit includes a first positive temperature coefficient (PTC) resistor, a first switch unit, and a second switch unit. The power conversion circuit includes a direct current bus, and the direct current bus includes a positive direct current bus and a negative direct current bus. The first switch unit is connected between a power supply and an input end of the power conversion circuit or is connected in series on the direct current bus of the power conversion circuit. The first PTC resistor is connected in parallel to the first switch unit. The second switch unit is connected in parallel between a positive port and a negative port of the input end of the power conversion circuit or is connected in parallel between the positive direct current bus and the negative direct current bus.
