Abstract
A current detection method adapted to an inverter is provided, which includes: determining that a plurality of lower arms of an inverter have a minimum conduction period when all the lower arms are turned on simultaneously; determining a sampling time point according to the minimum conduction period, wherein a period from a starting point of the minimum conduction period to the sampling time point is defined as a sampling period that is close to the minimum conduction period; simultaneously detecting currents flowing through the lower arms by a plurality of detection resistors to generate a plurality of measurement voltages; and determining the currents of the inverter according to the measurement voltages.
