Abstract: 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.

Abstract: 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.
