Abstract
A cascaded H-bridge inverter and a method for handling a fault thereof are provided. An output voltage or an output power of each of N solar panels is detected by a controller. In a case that the output voltage of at least one of the N solar panels is lower than a preset voltage, or that the output power of at least one of the N solar panels is lower than a preset power, the controller controls a corresponding switching device to be switched off, and changes a set value of a voltage across a capacitor in the direct current side. Then, the controller controls a corresponding H-bridge module to perform inverting by taking the set value of the voltage across the capacitor in the direct current side as an input value, so that a total output modulation voltage of the cascaded H-bridge inverter meets a preset condition.
