The voltage restorer is an equipment that employs PWM sinusoidal wave producing method using IGBT and the realtime monitoring of system voltage using DSP controller. The core portion of the equipment is composed of the super capacitor which stores energy, the thyristor bypass for switching of the system and load in case of power deterioration, the IGBT stack which produces sinusoidal wave voltage, the DSP for realtime control, and power circuit. Voltage quality of the system is monitored in realtime. Normally, system power is supplied through thyristor bypass. In case of an accident, power source and load are switched immediately, IGBT stack produces sinusoidal wave while the load side keeps an optimum power condition.
