And the steady-state consumption current of the gate driver is about 10mA. Therefore the gate average current must be less than 90mA. Please calculate the gate average current by the following expression. Idrive = (Q1＋lQ2l ) X ｆ Idrive : Gate average current Q1 : Gate charge on plus bias (Please read it from data sheet of IGBT) Q2 : Gate charge on minus bias (Please read it from data sheet of IGBT) f : Switching frequency (2) Electric power setting of gate resistance At the time of the choice of gate resistance, please choose the resistance which can permit the electric power by the following calculation. Pd = Idrive X 24 Pd : Total allowable power loss of gate resistance Idrive : Gate average current 24 : Total output voltage of gate power supply http://www.idc-com.co.jp Part arrangement & Size 3.5 φ DC-DC Converter VLA106-15242 Gate Resistor (This part is not installed at the time of shipment) 65mm Screw hole CONNECTOR 3.75mm CONNECTOR 3.75mm Gate Driver VLA513-01R 95mm http://www.idc-com.co.jp
