The invention discloses an alternating current charging pile PWM signal generator for a test. The generator is mainly used for an interoperability test of an electric vehicle and is used for simulating and outputting alternating current charging pile PWM signals, thereby enabling the electric vehicle to judge the charging pile cable carrying capacity and charging pile output capability. And moreover, the generator is used for simulating faults such as the duty cycle overlimit and frequency overlimit of the alternating current charging pile PWM signals. The generator comprises a shell; an operation display module which comprises a duty cycle display module, a frequency display module, a duty cycle adjustment module corresponding to the duty cycle display module, and a frequency adjustment module corresponding to the frequency display module, wherein both the duty cycle adjustment module and the frequency adjustment module comprise an automatic adjustment unit and a manual adjustment unit; and a PWM signal outp
