Abstract
An inverter control method, apparatus and device are provided, so as to solve the problem of risk of damage to switching devices in an inverter due to delays. The method includes: in a first switching period, determining a current change duration based on a time instant at which an inductor current in an inverter is equal to a first current threshold and a time instant at which the inductor current is equal to a second current threshold; determining a current change rate based on the current change duration, the first current threshold, and the second current threshold; reducing the first current threshold and the second current threshold if the current change rate is greater than a preset threshold; and controlling a switch by using the reduced current thresholds in a second switching period.
