摘要： Disclosed in the present disclosure are an insulation resistance detection circuit, a resistance detection method, a converter and a photovoltaic centrifuge. The insulation resistance detection circuit includes a resistance detection module connected between a positive electrode and a negative electrode of a direct-current bus to be detected. The resistance detection module includes a first resistance bridge and a second resistance bridge arranged in parallel. The first resistance bridge is connected to the positive electrode of the direct-current bus by means of a first sampling resistor R1. The second resistance bridge is connected to the negative electrode of the direct-current bus by means of a second sampling resistor R2, and both the first sampling resistor R1 and the second sampling resistor R2 are equipped with voltage sampling chips. The resistance detection module is configured to calculate an insulation resistance value of the direct-current bus according to voltage values of the two sampling resistors before and after a first switch S is switched.
