    KL MMA160 inverter igbt arc welding machine does not weld although it gives an appropriate value of 52 output voltage

    The output of the KL MMA 160 inverter igbt arc welding machine is 52 Volts and as it should be. The fan is also working. 4 High-Speed Switching Diodes (1N 4148 5T) diodes exploded on the Transformer Rectifier circuit card of the machine, I replaced them with new ones, but it still does not...

    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...
