Abstract: Systems and methods are provided for producing optimized electronic components. Particularly, the systems and methods may involve the use of a “three-legged approach” for determining design parameters for electrical components (and/or insulation of the electrical components) such that the electrical component is not subject to partial discharges (PDs) at a maximum operating voltage of the electrical component. The approach may involve extracting maximum bulk (e.g., orthogonal) and surface (e.g., tangential) electrical stress (e.g., electrical field) information at operating temperatures, comparing the values of these electric fields with electric field values that are likely to cause the inception of one or more PDs in the electrical component (which may be determined through modeling), and linking these results with PD measurements (such as the surface partial discharge inception voltage, SPDIV).

Abstract: Within a direct current hybrid circuit breaker (DC HCB), a commutation unit (CU) is provided in a semiconductor switch path in series with a semiconductor switch to facilitate opening the DC HCB. The semiconductor switch path is connected in parallel with a mechanical switch path that includes a mechanical switch. The CU is a controlled voltage source which applies a reverse biased voltage on the semiconductor switch path. The CU causes the current through the mechanical switch to ramp down while the current through the semiconductor switch ramps up to a supply current. The CU maintains the current through the mechanical switch to remain at a zero vale by compensating for the voltage drop across the semiconductor switch and the self-inductance of the semiconductor switch path. The mechanical switch can open without current and against no recovery voltage.

Abstract: A controller hardware in the loop (CHIL) interface is disclosed. The CHIL interface comprises software and hardware that redirects a signal flow, including modulation signals and measurements exchanged between controller logic and a power electronics converter (PEC), to a CHIL port. Accordingly, the CHIL port provides access to the controller logic, at a digital level, throughout phases of the controller's lifetime (i.e., design, installation, maintenance, upgrade). Thus, the CHIL interface facilitates the use of PEC simulators for testing. The CHIL interface can detach the actual PEC from the control logic so testing can be performed with or without an operating PEC and can avoid the need for dedicated and error prone signal conditioning circuitry that is external to the controller.
