Sažetak
Discrete Pulse Width Modulated controller for buck converter is described. The key building blocks are Analog to Digital converter, compensator, and digital pulse width modulator is introduced to meet the requirement of perfect output voltage regulation, high-speed dynamic response, and programmability. The discrete controller method bypasses errors related to the conversion from the continuous to the discrete domain based on the time domain method. The simulation results are proven with experiment conducted. Analog controller is also designed for a buck converter whose controller parameters are compared with the Discrete PID controller is illustrated
