Half-bridge driver giving high-side gate full input voltage
Turns out my scope probes were placed incorrectly. I was measuring from HO to Gnd and should have been measuring from HO to VS.

TC4420 MOSFET Driver Output Latching Behavior
The TC4420 push-pull MOSFET driver seems to latch its output on if the low input signal isn’t pulled to ground. The signal I am using for the input is purely an on-off signal where the off part of the …

Half-bridge driver giving high-side gate full input voltage
Using an IRS2513 half bridge driver tuned at 30 kHz with 1MBH60-100 1000 V, 60 A IGBTs, the driver is giving the high-side gate the full 24 V input voltage.
I have included a picture of how I configur …

While testing unloaded half-bridge, driver self-destructs
I have an IRS2153D configured so that the driver power supply is separate but not isolated from the half-bridge power supply. As soon as I place 12 V across the unloaded half-bridge, the driver bricks …

Half-bridge driver ground loop elimination
I built this half-bridge driver using a generic Schmitt trigger/hex inverter IC and a 555 timer as the square wave generator. By varying the value of the resistors, the dead time can be adjusted and i …
