摘要： Systems and methods are provided for monitoring current in an electric motor. An electrical system includes a (DC) interface, an electric motor, an inverter module coupled between the DC interface and the electric motor, a first current sensor between a first phase leg of the inverter module and a first phase of the electric motor to measure a first current flowing through the first phase of the electric motor, a second current sensor between the first phase leg and the DC interface to measure a second current flowing through the first phase leg, and a control module coupled to the first current sensor and the second current sensor. The control module is configured to initiate remedial action based at least in part on a difference between the first current measured by the first current sensor and the second current measured by the second current sensor.

摘要： Methods and apparatus are provided for improved discharge of a DC bus which provides power to an inverter. An electric motor system provided with the improved discharge method for discharge of the DC bus includes an electric motor, the inverter which provides electric control for the permanent magnet electric motor, the direct current (DC) bus which provides power to the inverter, and a processor. The processor generates operational control signals and provides such operational control signals to the inverter. In response to detecting a predetermined discharge signal, the processor generates operational control signals for generating a ripple current in motor windings of the electric motor to dissipate energy from the DC bus through a passive load, the passive load including the motor windings of the electric motor.

摘要： A power module system for a vehicle includes a circuit board, a power transistor mounted to the circuit board, and a temperature sensor mounted to the circuit board in a sensing location remote from the power transistor. The temperature sensor is configured to measure a real-time temperature at the sensing location. The system also includes a processor coupled to the temperature sensor to generate a predicted real-time silicon temperature for the power transistor from the measured real-time temperature at the sensing location. The predicted real-time silicon temperature is generated using a selected calibration curve that corresponds to a current operating state of the vehicle.

摘要： The invention relates to a method of shaping an ophthalmic lens to have a desired outline (11) by means of a machining device including a blocking support for the ophthalmic lens and at least one first machining tool, the method comprising the steps of: obtaining an inner cutting limit (12) for said first machining tool; defining an initial blocking position (P1) for the ophthalmic lens and its desired outline; calculating whether at least a portion of the desired outline presents a non-zero intersection (Q21-Q22) with said inner cutting limit; defining as the final blocking position (PF) either the unchanged initial blocking position if the intersection calculated the calculation step is zero, or else a blocking position that is modified relative to the initial blocking position so that the desired outline as repositioned using the modified blocking position does not present an intersection with the inner cutting limit associated with the first tool; and blocking and shaping the ophthalmic lens with the desired outline.

摘要： Systems and apparatus are provided for capacitor segments for use in a vehicle. A capacitor segment comprises an inner conductor configured to receive a first potential and having a generally L-shaped longitudinal cross-section. An outer conductor is configured to receive a second potential, and is electrically insulated from the inner conductor. The outer conductor comprises a first section having a generally L-shaped longitudinal cross-section aligned with the inner conductor, and a second section coupled to the first section and having a generally L-shaped lateral cross-section. The second section and the inner conductor define an inner region. A capacitor is located in the inner region and coupled to the inner conductor and the second section. The capacitor segment is configured such that current flows through the capacitor in a first direction, and current flows through the second section in a second direction that generally opposes the first direction.
