Real Time Control Hardware in The Loop test of a novel MVDC solid-state breaker

This paper assesses the development of a novel solid-state MVDC breaker and current limiter. Matlab/Simulink simulations are used as benchmark, then Real Time Control Hardware In the Loop (CHIL) simulations are performed. Same control algorithm is implemented into a microcontroller by using two different software languages: C and MicroPython. In both cases, high performances are achieved by using fast features like hardware interrupts and low level assembler code. Results are then compared in terms of simplicity, ease and speed of implementation and code readability, very important in fast prototyping activity.
