Input control method

Abstract

This invention discloses an input control method that sets the maximum values ​​of the input and output voltages of an energy recovery system. Next, an input voltage equal to the maximum value is input to the energy recovery system, and the input power is controlled to increase gradually from 0 in fixed increments to calculate the first maximum duty cycle of the main control signal corresponding to the input power when the output voltage equals the maximum value. Then, the input power is controlled to increase gradually from 0 in fixed increments, while the input voltage decreases gradually from the maximum value in fixed increments to calculate the second maximum duty cycle of the main control signal corresponding to the input power and input voltage when the output voltage equals the maximum value. Finally, multiple duty cycle and input power curves corresponding to different input voltages are generated based on the calculation results, and the energy recovery system is controlled accordingly.
