Digital Sine Oscillators Based on Higher Order Sigma–Delta Modulation

IEEE Transactions on Instrumentation and Measurement, 2022
In this article, a new class of digital sine oscillators based on higher order multibit sigma–delta modulation is presented. The samples of a given pure sine signal are quantized, resulting in a pulse-code modulated (PCM) sequence.

Hardware Implementation of a SiC Three-Phase Four-Leg VSI with Sigma-Delta Modulation to Comply with the Military Standards 1399 and 461

European Conference on Cognitive Ergonomics, 2022
This paper demonstrates sigma-delta pulse density modulation without common mode voltage in a four-leg voltage source inverter built with SiC MOSFETs and controlled by an FPGA. The converter does not produce common mode voltage in the switching frequency
