Publication number: 20230089458Abstract: A gate drive circuit of a wide band gap power device (IGBT) includes a buffer, a di/dt sensing network, a turn-on circuit portion and turn-off circuit portion. The buffer, responsive to turn-on, supplies a first current via the first current path to the gate of the IGBT, and responsive to turn-off ceases the supply of the first current. The di/dt sensing network receives a feedback control signal representative of a voltage measurement across a parasitic inductance that exists between a Kelvin emitter and a power emitter of the The turn-on circuit portion, responsive to turn-on and a parasitic inductance of zero volts, supplies a second current via a second current path to the gate of the IGBT. The turn-off circuit portion, responsive to turn-off and a parasitic inductance of zero volts, discharges a gate capacitance of the IGBT through both the first current path and a third current path.Type: ApplicationFiled: March 5, 2021Publication date: March 23, 2023Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Yash Veer SINGH, Armen BARONIAN, Piranavan SUNTHARALINGAM, Mikhail GOYKHMAN, Galen CHUI

Publication number: 20230003765Abstract: A current sensing system includes a pre-calibrated busbar, a voltage sensor, a temperature sensor and a controller. The pre-calibrated busbar has a known resistance, a known variation in resistance with respect to temperature and known dimensions. The voltage sensor detects a difference in voltage between a first location and a second location on the pre-calibrated busbar. The temperature sensor detects an ambient temperature of the pre-calibrated busbar. The controller determines a resistance of the busbar between the first location and the second location based on the known resistance, known variation in resistance, known dimensions and the ambient temperature. The controller additionally determines a current flowing through the pre-calibrated busbar based on the difference in voltage and the determined resistance. The current sensing system has numerous applications including using the determined current to control an operating condition of a solid state circuit breaker or a solid state power controller.Type: ApplicationFiled: November 25, 2020Publication date: January 5, 2023Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Armen BARONIAN, Yash Veer SINGH, Piranavan SUNTHARALINGAM, Mikhail GOYKHMAN, Galen CHUI
