Hi Ti Team,
I want to build a full bridge circuit to drive a step up transformer for programmable variable frequency power inverter on in simple term programmable power amplifier.
I only have 24 V power supply available to me, as this design will be fitted in tight enclosure and entire system will be power by 24V lithium ion battery.
I need to build a full bridge which will be powered by this battery and the outputs of full bridge will be connected to a step up transformer. My input to the system will be from micro controller which will generate a complimentary variable duty cycle PWM signals. Since my VDS is 24V, and to ensure very smooth switching action to happen I need a gate driver with following specifications:
- Configuration: Half Bridge or Full bridge
- Mosfet Drive voltage: 24V (The bridge is powered from 18-25.4 Volt battery)
- Gate Driver supply voltage: 15V
- Type: Isolated
- Protection and Features: Power good, active miller clamp, in built bootstrap diode, short circuit and undervoltage and over voltage protection, dead time control preferably 100 nS.
Reason I want to use active miller clamp is to negate the use of negative power supply. Please guide me.
