| Abstract: | In order to improve current wave in transmitter, a new passive non less snubber is designed through two methods. The first one is that the changes in parameters of inductance loop can improve transmitting current wave, and the turn off current wave declines linearly. The other is that the changes of driving signal can also smooth the wave. The experiment results show that two methods are both feasible. |
