摘要：Disclod is a multi-level inverter, wherein same falls within the field of power electronics. The multi-level inverter compris a main topology, at least four resistive devices, a switch device and a controller, wherein the main topology compris a power source, a flying capacitor and at least four miconductor switch devices; the flying
capacitor is electrically connected to the power source; the switch device and a resistive device are arranged on a connection line between a first end of the flying capacitor and the positive electrode of the power source; the switch device and a resistive device are arranged on a connection line between the first end of the flying capacitor and the negative electrode of the power source; the switch device and a resistive device are arranged on a connection line between a cond end of the flying capacitor and the positive electrode of the power source; the switch device and a resistive device are arranged on a connection line between the cond end of the flying capacitor and the negative electrode of the power source; and the controller is ud for controlling the closing of the switch device before the main topology works, and for controlling the disconnection of the switch device when it is detected that charging of the flying capacitor is completed. By means of the prent invention, a miconductor switch device can be prevented from being damaged.
