    The present invention discloses a switching driving method used for a driving system. The driving system transforms any type of waveforms to switching signal array by switching strategy modulation, and transmits to switching circuit. Any type of driving waveforms can be generated through high-speed switching the switching circuit. The waveforms can be generated by operating the switching circuit with the switching strategy. The losses of the switch can be reduced, and the modulation ability of driving signal having several waveforms and multi-channels can be improved.
