Power converter and wave generation control method thereof

The invention provides a power converter and a wave sending control method thereof. The power converter comprises a transformer, an inductive device, a primary side circuit, a secondary side circuit, a microcontroller and a signal analyzer. Wherein the primary side circuit and the secondary side circuit comprise at least one switch tube. The microcontroller sends a control signal and a dead zone signal to the signal analyzer, and the signal analyzer generates a pulse rising edge of the PWM signal at the moment after the pulse rising edge of the control signal delays the pulse width length, and generates a pulse falling edge of the PWM signal at the same moment as the pulse falling edge of the control signal; or, the pulse falling edge of the PWM signal is generated at the same moment of the pulse rising edge of the control signal, the pulse rising edge of the PWM signal is generated at the moment after the pulse falling edge of the control signal delays the pulse width length, and the pulse width length is in
