Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Without substantial compensation, conventional phase-locked loops (PLLs) and estimators might suffer a loss of synchronization with the rotor position. This paper presents an enhanced PLL (EPLL) for ...

The pull-in process is a mechanism where phaselocked loop acquires lock state. It is known as the highest range of frequency where the phase locked loop (PLL) has a separatrix cycle. No exact formula ...
