Abstract：The influence of control delay, resolution of A/D converter, resolution of PWM, and sampling and holding of digital control of switching converter are discussed. Then a more accuracy model is brought forward considering the influence of control delay and sampling and holding. Theory and simulation analysis of control time delay is carried out after the transfer function of the inverter is produced. The experiment on a 500VA 210VDC/115V 400Hz inverter prototype verified the validity of the controller’s design.
