• This paper introduces a variable resistance type energy regenerative suspension using PWM step-up chopper. The energy regenerative suspension has nonlinear characteristics with dead zone for low speed motion. Hence the energy is not regenerated nor has it damping force. In order to overcome this problem, a step-up chopper is introduced between the actuator and the charging circuit. This chopper is controlled by velocity-dependent PWM signal to improve the damping characteristics and the efficiency of the regenerative suspension. The suspension system changes its height according to the carrier load. Hence linear AC motor is used to the isolation actuator. A simple experiment is performed. The results show better performance than the standard regenerative suspension.
