Provided here is a soft start circuit for an inflation pump motor, including a control module, a motor drive module, an air pressure detection module, and a voltage detection module. The control module outputs a first control signal to the motor drive module to drive a motor. The control module dynamically adjusts a duty cycle of the first control signal based on real-time feedback of a load air volume and a voltage, gradually increasing motor current to a rated operating current. This PWM-based voltage ramp soft start method allows a motor terminal voltage to rise gradually and smoothly from zero instead of directly applying a full voltage. The above structure solves a technical problem that the inflation pump cannot start due to an excessive inrush current causing power supply protection, and reduces a burden on a power supply.
