The invention relates to an intensive SVG (static var generator) power unit driving board which is capable of improving the quality of a power network and used in an electric power system. The intensive power unit driving board is characterized in that a main control unit is adopted as a core, a triggering signal of a control system is received, control signals for upper arm bridges and lower arm bridges are formed, current state signals of IGBTs (insulated gate bipolar translators) of the upper arm bridge and the lower arm bridge are received synchronously, an overvoltage fault signal, a normal driving signal and an undervoltage fault signal can be obtained by detecting voltage at two ends of a capacitor, the temperature of a SVG power unit is monitored in real time, and an overtemperature fault signal is received. The intensive power unit driving board has the advantages that stable control is provided for the power unit of an intensive SVG device, dynamic, quick and continuous reactive output adjusting can be achieved via an SVG control system, and requirements of power factor compensation are satisfied maximally.
