    摘要： A system for controlling a commutation of a load current is provided. The system comprises a AC-to-AC converter that includes a plurality of switching elements, an energy source that provides an oscillating voltage and is connected to the converter, an electrical load connected to the converter, and a controller that controls the converter, and monitors the oscillating voltage and the load current delivered to the electrical load. The controller determines a plurality of machine states of the converter, each of the plurality of machine states representing a corresponding conducting set of the plurality of switching elements, and controls switching between the plurality of machine states based on polarity commutations of the load current in the electrical load and polarity commutations of the oscillating voltage.

    摘要： A control circuit is described in which a single input terminal receives digital control signals and analog control signals. In accordance with the principles of the invention, the control circuit includes an automatic power down circuit to place the control circuit into a low power draw or “sleep” mode whenever predetermined conditions are present. The automatic power down circuit monitors the single input terminal and when no demand for motor operation occurs for a predetermined period of time, the automatic power down circuit operates to place the control circuit into the low power draw mode.

    摘要： The invention relates to a method for operating an electric machine (4), in particular of a motor vehicle (1), having a stator (10) with at least one stator coil. The stator coil is energized in order to set a required torque of the electric machine (4), and a temperature of the stator (10) of the electric machine (4) is detected by means of a temperature sensor (12). The current flowing through the stator coil is monitored in order to plausibility-check the detected temperature. In order to plausibility-check the temperature, the current in the stator coil is increased while maintaining the same torque, and the temperature is monitored for a temperature increase.
