There are many advantages for the grid electrode driving circuit by using the pulse transformer. For example, the pulse transformer can make up a simple grid electrode isolated circuit and do not distinguish the high and low side driving circuit. The pulse transformer could also transmit the power, and the high-side driving circuit does not need the auxiliary power. The grid electrode driving conditions could be set freely.The high and side driving circuit could use the circuit with the same structure. In half-bridge circuit it could use the pulse transformer to make up the symmetrical drive circuit and so on.The picture shows the grid electrode driving circuit by using the pulse transformer. This circuit pulse transformer T1 could use the center tap method, and do the switching work by the transistor or power MOSFET. It is always used in the positive excitation conversion's switching power.
