@conference{10902/10903, year = {2016}, url = {http://hdl.handle.net/10902/10903}, abstract = {New power factor correction (PFC) stages such as bridgeless converters and the associated current shaping techniques require grid synchronization to ensure unity Displacement Power Factor (DPF). Sensorless line current rebuilding algorithms also need synchronization with the line voltage to compensate at least for part of the current estimation error. The application of a secondary control path to reach faster and more robustly the proper operation point previously applied in single/three-phase PLLs in grid connected converters is here proposed for the current sensorless bridgeless PFCs. This work analyzes the performance of three single-phase T/4 PLL structures, first without secondary control path, and later with feedforward and feedback secondary control paths, both in simulation and experimentally, and evaluates their applicability to current sensorless digitally controlled single phase bridgeless PFCs based on the current rebuilding technique.}, organization = {This work has been supported by the Spanish Ministry of Economy and Competitiveness under grant TEC2014-52316-R ECOTREND Estimation and Optimal Control for Energy Conversion with Digital Devices.}, publisher = {IEEE}, publisher = {IEEE 17th Workshop on Control and Modeling for Power Electronics (COMPEL), Trondheim, Norway, 2016, 8-12}, title = {Performance analysis of 1ϕ T/4 PLLs with secondary control path in current sensorless bridgeless PFCs}, author = {Lamo Anuarbe, Paula and López Vidal, Felipe and Pigazo López, Alberto and Azcondo Sánchez, Francisco Javier}, }
