Stability and performance assessment of single-phase T/4 PLLs with secondary control path in current sensorless bridgeless PFCs

Bridgeless power factor correction (PFC) stages and the associated current shaping techniques require grid synchronization to ensure unity displacement power factor. In controllers with no current sensor, line current rebuilding algorithms are especially sensitive to synchronization issues. Phase-lo...

This paper presents linear models of T/4 PLLs with secondary control paths. The T /4 PLL structures are digitized and their performance evaluated. The stability conditions are determined.
