| Popis: | 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 Opisan je diskretni pulsno-širinsko modulirani regulator za silazni upravljač. Osnovni dijelovi su analogno-digitalni pretvornik, kompenzator, a predložen je i diskretni pulsno-širinski modulator kako bi se što bolje upravljalo izlaznim naponom i imao što brži dinamički odziv. Diskretni regulator nadilazi pogreške povezane s prelaskom iz kontinuirane u diskretnu domenu. Simulacijski rezultati su potvrđeni eksperimentom. Projektiran je i analogni regulator za silazni upravljač te je napravljena usporedba s diskretnim PID regulatorom. |
