    LTspice inconsistent MOSFET gate driver behavior

    Hello, I am working on a 7-level power micro-inverter which composed mainly by power MOSFETs. These logic-level MOSFETs (IRLZ24NS) are driven by separate photovoltaic gate drivers with integrated fast turn-off (Broadcom ACPL-K30T). The problem comes when I try to simulate the circuit and compare...

    Gate driver for two switch forward converter

    I'm trying to understand how to drive the MOSFET's in the two-switch forward, I designed a 200W DC-DC converter, 50V input 100V output but I was looking for using an MCU and IC in this case I have an IR2110 high side low side for the gate drive, I don't know if it is possible to use it? and if...

    Strange voltage spikes in MOSFET gate driver

    Hello, I have designed a TL494 half bridge power supply which simulates fine in LTspice but has some problems when soldered on a board and I can not figure out how to fix them. Schematic pictures are attached. 1. If I connect GDT1 and GDT2 as seen in the schematic pictures, the output...

    IGBT Gate Driver Selection

    Hello, I'm designing a resistive load bank. Currently, I am designing the switch that will be controlled by a control signal via Arduino uno rev 3. The bidirectional switch is composed of two back-to-back igbts connected by their emitters with anti-parallel diodes. (Due to cost, there are two...

    High Side Gate Driver Connections.

    Referring in particular to pages 23, 27 and 33 of the attached datasheet for isolated gate driver UCC 5390 S [from TI] to be used to power the high side gates of IGBTs in an H-Bridge module, is it correct that the 5V input to the VCC1 pin may be provided by an MCU [PVM], as suggested by the...
