Abstract�� To reduce the ripple current of standard two-level pulse width modulation (PWM) switching power amplifier for magnetically suspended flywheel system, a novel three-level PWM switching power amplifier was proposed. The ripple current of the switching power amplifier using two different PWM techniques was computed. The analysis results of ripple current indicate that the three-level PWM switching power amplifier can be used to significantly reduce the ripple current and meet the requirement for low power consumption. A novel simulation method of three-level PWM switching power amplifier was presented, based onSIMULINK. The method can analyze the characteristics of the system accurately and so offer direction for designing and debugging actual switching power amplifier. The comparison of a concrete switching power amplifier working in different PWM techniques by using simulation and experimental method was made. The agreement of the final simulation results with the experimental results indicates the proposed method is effective and feasible.
