Designing a phase-locked frequency control system

The article is devoted to the development of a phase locked loop (PLL) system using the CD4046 integrated circuit. To achieve this goal, the principles of operation of two types of phase detectors were investigated. In the second half of the article, the main transfer functions of the PLL system are derived, an example of calculating the feedback controller is considered. The reliability of the calculation results is confirmed by modeling a computer model of a resonant voltage inverter.
