Infineons gate driver IC solutions are the experts choice. I would guess that the common power supply might be the problem?, or it might be that the switching frequency of 125kHz the problem? The Hin and Lin signals are PWM signals with 15 V peak. A single input pin on the LT1158 synchronously controls two N-channel power MOSFETs in a totem pole configura-. Half bridge gate driver ICs with shoot through protection, to control MOSFETs and IGBTs. I would like to note that the chip is FAN7390.

The MOSFETs are generally controlled by a PWM chip of some sort. Another common solution is the half bridge driver, which involves a half bridge of MOSFETs supplied directly from rectified and filtered mains. An engineer in my uni suggested that the problem might be caused because I was providing the 15 volts to the MOSFETs from the same node that supplies the same voltage 15 V to my entire circuit, although my circuit was drawing only 40 milliamps from the power supply before connecting the MOSFETs. One very popular solution is Mazzili flyback driver, which is a circuit based on a powerful Royer oscillator with MOSFETs. As shown in circuit diagram, input DC voltage is Vdc 100 V. Circuit diagram of the half bridge inverter is as shown in below figure. The MOSFET or IGBT is used for switching purpose. When I connected the circuit without the MOSFET half-bridge, I grounded Vs and I got a neat output according to my needs 15 V peak at HO & LO, The problems started when I connected the MOSFETs, The HO & LO terminals started sending out the same signal but with a max voltage of 3 V or probably less, then the circuit drew around 1 AMP from my voltage source and burned the MOSFET driver chip, I knew for sure that it was burned because the resistance between the VDD terminal and the COM terminal was 26 Ohms instead of the high resistance a new chip had. This type of Inverter requires two power electronics switches (MOSFET). Now including the new 650 V half bridge silicon on insulator (SOI) gate driver ICs with high current (2.5 A) and low current (0.
#Half bridge mosfet driver drivers
We offer half bridge gate drivers with two interlocked channels. Infineon’s gate driver IC solutions are the expert’s choice. I am making a class D audio amplifier and I am using a MOSFET driver to control two MOSFETs in a half bridge configuration as shown in the circuit below Half bridge gate driver ICs with shoot through protection, to control MOSFETs and IGBTs.
