Evertiq - Driving a unipolar gate driver in a bipolar way
Driving a unipolar gate driver in a bipolar way Question: Do you need a specialized gate driver to deliver positive and negative voltages? Answer: No, you can adapt a unipolar gate driver to drive in a bipolar manner. If a positive and negative gate drive is required for a particular power device, circuit designers don’t need to search for a special gate driver that handles bipolar operation specifically. Use this simple trick to make a unipolar gate driver deliver bipolar voltages! When driving medium to high powered MOSFETs and IGBTs, there is a risk of a Miller effect induced turn-on whe...
