Method for improving operation reliability of current-control type inverter output short circuit

The invention discloses a method for improving the operational reliability of the output short circuit for a current control type inverter, belonging to an inverter. The inverter is provided with a low-voltage protective circuit and a standard voltage gate circuit based on the prior inverter, wherein a high-low level signal is obtained after the inverter output voltage passes through the low-voltage protective circuit, a control signal is obtained after a high-low level signal passes through the standard voltage gate circuit, an acquisition control signal for a voltage ring in a DC-DC module and the input voltage of the inverter for sampling output a PWM control signal, a drive signal of a power converter is obtained after the PWM control signal passes through a PWM driver, the power converter acquires the drive signal and receives the DC voltage outputted by a DC power supply, and the power converter adjusts the output voltage according to the drive signal, namely the input voltage of the inverter. The method has low loss of a switch and operates safely and reliably when the short circuit is outputted.
