WebAug 8, 2024 · This article presents a LTSPICE simulation of a PWM buck converter controlled by a discrete PID. The simulation result will be compared to the result of the actual implementation of a digitally controlled buck converter ( Buck converter ). Below table is a comparison of the source code from the the actual implementation (DSPIC33 IC) and … WebPiecewise linear (PWL) functions are used to construct a waveform from a series of straight line segments connecting points defined by the user in LTspice. Since PWL functions are useful in creating custom waveforms, they are typically used in defining voltage or current sources. To add a PWL function to a voltage or current source:
