This paper provides a comprehensive evaluation of the SSEE solution on both energy harvesting and motor braking aspects, in other words, regenerative braking performance. An SSEE circuit, which fulfills all tasks of current sampling, current synchronization, and switch control, is utilized in this study. By making the coil current in phase with the induced voltage source, the power factor is significantly improved. Therefore, the energy associated with the rotational motion is extracted much faster to quickly brake the motor, while a part of the energy is harvested into storable electrical dc energy. The control effort in SSEE, in terms of the number of switch actions, is much less than that in the conventional pulse-width modulation (PWM) counterparts. Experimental results show that, given a flywheel released from the same speed, the SSEE can reclaim 216.7% more energy than the diode-bridge rectifier, which is regarded as a standard energy harvesting (SEH) interface circuit. For the braking performance, the SSEE can reduce the braking time by 35.1%, compared with the short-circuit braking (SCB) case.
