A New 5L-UHPFC with Reduced Part Count for Wind Energy Intigration

In this paper, a new three phase 5-level unidirectional high-power factor converter (5L-UHPFC) for wind energy integration is proposed. The proposed converter has an advantage of reduced device count along with reduced maximum device stress. No bidirectional switches or clamping devises are used. However, the converter can be modeled and modulated similar to multi-point clamped (MPC) structured converters like diode clamped topology. The validation of the new 5L-UHPFC with phase disposition pulse width modulation (PD-PWM) scheme is verified by simulation and a down scaled experimental setup.
