In this paper a new zero voltage switching flyback current-fed push-pull converter with an active circuit is proposed. The active clamp circuit not only absorbs the voltage surge across the switches at turn off instant, but also provides zero voltage switching condition for all switches. Main switches are controlled by PWM scheme and the auxiliary switches(More)
The main function of power system stabilizer (PSS) is suppressing the low-frequency oscillation of the power system to improve the dynamic stability of power system. In this paper, the pole-placement approach and full phase-compensation method are used to design the parameters of a derivative power system stabilizer (DPSS) base on electrical torque(More)
