In this paper, the design and implementation of the new four-bridge P W M static phase shifter control system is described. The design examples are given and the design results are verified by the physical model simulation. By using the constant power control method, The transient simulation results of a single-machine-one infinite system show that the new four-bridge P W M static phase shifter can increase the damping torque of generator and restrain the power angle oscillation, For improving the transient stability of the system has a very positive role.
