ABSTRACT:
The power switch driver is a controlled 4-terminal device for substantially capacitive load, e.g power MOSFET. The switching speed, efficiency and reliability are very high. The switching frequency is inherently limited. The bias supply of the driver may be floating or grounded. The output voltage is approximately two times higher than supply voltage. The energy delivered to the capacitive load is recovered. The driver comprises an inductor for attaining a current and providing binary output voltage. One switch selectively applies the current having any polarity to the supply voltage source. Another switch selectively applies the current having one polarity to ground. A diode applies the binary output voltage having a reverse polarity to ground.
