Abstract

FPGA became a low-cost platform providing the possibility to design new EMC friendly control techniques for power electronics. However, some of the functions required in the power electronic control system are difficult to implement in FPGA. The main challenges are connected to the fixed-point operation, and the need to adjust the dynamic range of numbers. To provide design insights on this topic, the paper presents an FPGA-based random modulation technique intended for DC/DC converter for harmonic reduction. The presented random technique is compared with deterministic PWM in terms of harmonics reduction and FPGA hardware resources. The theoretical algorithms, hardware details, and experimental results are presented and discussed.
