用于微电网中风电并网的整流和逆变的门极的SPWM控制-The SPWM control gate of the rectifier and inverter for micro-grid wind power grid

电压型控制的IGBT不需要栅极驱动电流，但由于栅极输入端有一个大电容，使在驱动时形成一很窄的脉冲栅极驱动电流，且IGBT容量越大，该脉冲电流的峰值越大，例如，200A/1200V的IGBT的开通电流的脉冲峰值约达到1.5A。SKHI驱动器既能承受这种高峰值栅极电流-gate drive current, but because the gate input has a large capacitance, so that the formation of a very narrow gate d
