A new fast PWM modulation strategy for power electric converter based on finite set state machine theory

The finite set state machine theory belongs to the field of computer science. It is used to model and create multitasking systems. The control and modulation system for power electronics converters is a multitasking system as well. To increase the control speed without being constrained by the triangular wave module, the finite set state machine theory can be applied to converter modulation. In this paper, a modulation technique for finite state machines was proposed. This strategy fully uses the relationship between the affective state and converter switch states. Then, the structure of the modulation modular is presented in detail. This paper has analyzed the mathematical model of the finite set state machine modular. Finally, finite set state machine theory is used to Boost converter modulation modular to control the output voltage stability. Additionally, the effectiveness of the modulation strategy is validated by the experimental results. (c) 2023 The Author(s). Published by Elsevier Ltd.
