| Abstract: |
| Aiming at of the problem of reverse charging in the actual power amplifier circuit, an optimization solution of bidirectional discharge was proposed.And for the narrow adjustment range of the duty cycle of the driving signal caused by the coupling capacitor component in the circuit, a solution to remove the coupling capacitor and increase the anti-common conduction protection circuit was also put forward.The simulation and test of the optimized circuit are carried out.The results show that the optimized drive circuit can obtain a better dithered drive signal. |
