3-phase Bridge Inverter
In 3-phase bridge inverter six thyristors an six diodes are used as shown in figure a capacitor at input terminal is connected so that the input voltage remains constant. Let the load is 3-phase resistive load and it is star connected. According to pattern of gating the thyristor 3-phase inverter is of two type 3-phase 1800 mode VSI and 2-phase 1200 mode VSI.
