摘要： An inverter comprises output switches for generating motor phase currents for application to an electrical motor based on a commanded torque. A current sensor is arranged for detecting motor phase currents applied to the electrical motor by an inverter. A voltage sensor is configured for measuring voltages applied to the electrical motor by the inverter. An output port is capable of outputting output signals of the detected motor phase currents and measured voltages for processing by a vehicle controller. The output signals are suitable for input to a vehicle controller for determining whether or not to generate an override control signal. An input port is configured for receiving the override control signal from the vehicle controller. The input port is coupled to an override input module for switching off a supply of electrical energy to the electric motor.

摘要： A non-invasive, non-destructive method and system for determining power transistor peak die voltage utilizes values for each of a plurality of parameters determined by measurement of external terminal voltages for any number of switches, such as transistors of an inverter. Stray inductance values are calculated and used with measured current gradient to calculate the peak die voltages for the switches. A refinement of the method determines transistor peak die voltage without measuring current.

摘要： An electric vehicle is provided having an electric generator and a motor. A voltage bus including a DC link is configured to provide generated electrical energy to the motor. A controller may estimate the charging current to a capacitor of the voltage bus based on the current commanded from the generator and the voltage measured across the capacitor. The controller may adjust the charging rate of the capacitor based on the estimated charging current.

摘要： A device inserted between a grounded poly-phase external voltage source and a load providing low insertion loss for differential mode currents and high insertion loss for ground currents. The device receives voltages from the grounded poly-phase external voltage source over atone or more voltage lines. The voltages contain common mode voltages. A filter connected to each of the voltage lines reduces the ground current from the load. A summing block adds the voltages from each of the voltage lines to generate a total common mode voltage. A ground referenced controlled voltage source generates a cancellation voltage equal to the total common mode voltage in response to the generation of total common mode voltage. The total common mode voltage is injected into the filter and substantially reduces the common mode voltage on each voltage line thereby substantially reducing the ground currents associated with each common mode voltage on each voltage line.
