This gate current can be calculated using the equations for IGBT input capacitance charging. On this page, we present the most frequently used electronics equations that address how to design circuitry with capacitors. Presently the term is reused for all power devices, including gate isolated devices like power MOSFETs and IGBTs. 3V, then a loss of 0.
