Should a torsion spring be used for energy storage?
The concept of using a torsion spring as a means of mechanical energy storage before the energy conversion to electricity has the substantial benefit of being able to directly capture and accumulate all input motion, even in the event of sudden impacts, and then convert this mechanical energy through a motor to provide a smoothed electrical output.
Can an energy harvester power multiple micro devices?
It has been claimed that the current energy harvester is able to power many micro devices, for example, multiple sensors. Modern devices are increasingly complicated and may contain several or numerous components or modules to complete the full functionality.
How UD & UQ are used to drive a motor?
Then ud and uq are adopted to get the three-phase voltages ua, ub and uc which are used to drive the motor by using Park inverse transformation and standard space vector pulse width modulation (SVPWM). In this way, the double closed vector control of the motor’s current and rotating speed is realized. Fig. 5.
