A system and method for hardware tamper detection and mitigation for a circuit breaker. The method includes detecting and mitigating a breach to a circuit breaker of an electrical power management system, wherein the circuit breaker includes a housing, an electrical circuit, and switch coupled to and controllable by the electrical circuit. An alert identifying a detected breach event at the circuit breaker is generated and transmitted to a computing device. The circuit breaker device experiencing the detected breach event is disabled in response to the alert. An electrical power management system includes a plurality of circuit breakers each having a breach detector coupled to an electrical circuit, and a switch coupled to and controllable by the electrical circuit. A circuit breaker controller controls the state of the circuit breaker as determined by the breach detector.

Method and system for hardware tamper detection and mitigation for solid state circuit breaker and its controller

Unique systems, methods, techniques and apparatuses of an active neutral point clamped converter (ANPC converter). One exemplary embodiment is a power conversion system comprising a grid-side converter, a DC link, a multi-phase ANPC converter coupled to an electric machine, and an electronic control system. The electronic control system is structured to selectably operate in a first mode and a second mode in response to a device failure state of the ANPC converter, the first mode operating the grid-side converter to provide a first DC link voltage and operating the ANPC converter using a first modulation index, and the second mode operating the grid-side converter to provide a second DC link voltage greater than the first DC link voltage and operating the ANPC converter using a second modulation index lower than the first modulation index.
