Abstract

In this paper, a novel building algorithmic scheme of DDCM (duty-cycle modulation) drivers is presented. It is modelled in the analog domain as a continuous time jump Markovian dynamic model, with a deterministic two-state Markov chain. An equivalent discrete jump dynamic model is computed using pole-zero matching transform. Then, the resulting digital iterative algorithm, consists of simple digital operators and structures. The proposed DDCM algorithm is simulated under Matlab framework, and implemented using Arduino IDE-C++ with uploading into an ESP32 system-on-chip (SoC) device. The monitoring device connected to the ESP32 via an USB communication cable is an Arduino/IDE virtual monitor. It is configured for 230400 bauds communication. A low cost ESP32-based DAC (digital-to-analog converter), is virtually implemented and well tested as a case study of the proposed new generation of DDCM drivers. Matlab digital simulation results and ESP32 processing and virtual monitoring results are presented and discussed, in order to show the realistic nature and the great challenge the proposed DDCM algorithmic scheme for SOC devices.
