Embodiment Construction
[0014] Such as figure 1 shown. figure 1 The working process of the schematic block diagram shown is as follows: After the driving signal passes through the damping and elimination circuit to eliminate the long-term oscillation, it is sent to the high-current buffer driving circuit for current expansion processing, and the transient driving current capacity is extended from milliampere level to ampere level; The damping and vibration elimination circuit is input to the primary of the isolation coupling transformer, which has the characteristics of high-voltage isolation and good coupling. The push-pull amplifier circuit and channel conversion isolation circuit with completely consistent device parameters, the push-pull amplifier circuit can avoid common conduction, and the channel conversion isolation circuit can avoid mutual interference between turn-on and turn-off; the driving signal has undergone the above-mentioned series of optimization processes Finally, they are sent t...
