摘要： The invention relates to a method for detecting a control method of an inverter (11) for supplying current to an electric machine (1), in particular a synchronous machine, having N phases. The method comprises sensing a control signal (CU, DU, CV, DV, CW, DW), which is fed to the inverter and which is clocked with a periodic cycle, over a specified number of periodic cycles of the control signal; determining a duty cycle frequency for the sensed control signal over the specified number of periodic cycles; and detecting the control method on the basis of the determined duty cycle frequency. The invention further relates to a device (5) designed to perform the method. In addition, the invention further relates a use of the method or of the device to monitor a torque of the electric machine and in particular to estimate an operating-point-dependent power loss of the electric machine according to the detected control method.

摘要： An indicator arrangement includes comparators for parallel comparison of an analog input voltage with digitalizing standard voltages to digitalize the input voltage and an indicator for indicating digitalized output. The arrangement is provided with a controller periodically switched between a first control state and a second control state. The controller in the first control state allows the comparators to perform comparison in a first voltage range of the analog input voltage while in the second control state it allows the comparators to perform comparison in a second voltage range of the analog input voltage.There is provided an encoder for coding the digitalized output of the comparators with a first coding mode in the first control state of the controller and coding the digitalized output of the comparators with a second coding mode in the second control state. The encoder is adapted to drive the indicator with a first or second mode according to the state of the controller.

摘要： The switching device delivers an electrical output signal having a mean amplitude which changes progressively from the amplitude of a first signal to that of a second signal. One control signal produced by a logical unit is applied to each control input of a switching unit for closing or opening the switches of the switching unit. The control signal is given a first logical level during a first period and a second logical level during a second period. During an intermediate "switching" period the signal is given alternately the first logical level and the second logical level with a predetermined frequency. The time-duration of the half-waves of the first logical level thus decreases progressively when passing from the first period to the second period.

摘要： A pair of incandescent lamps coupled to the output of a trigger circuit included in the input channel of an electronic measuring instrument. The trigger circuit is actuated by an input signal to provide a pair of complementary output signals wherein each output signal is characterized by a duty cycle which is a function of the relative amplitudes of the input signal and a threshold voltage which is applied to the trigger circuit. Each lamp is adapted to monitor one of the complementary output signals and emit visible light having a radiant intensity which is a function of the duty cycle of the output signal.

摘要： Embodiments include apparatuses, systems, and methods including a switching converter having an output stage including a power switch or first switching device to convert an input switching signal to an output switching signal and a sensor stage including a second switching device and a third switching device. In embodiments, the sensor stage may be coupled to receive the output switching signal from the first switching device and to substantially replicate a condition of the first switching device to generate a continuous signal rather than a switched signal. In embodiments, the continuous signal may allow detection of a current level. In some embodiments, the current level may indicate an overcurrent event. A digital post-processing circuit may be coupled to the switching device to count a number of overcurrent events according to various embodiments. Other embodiments may also be described and claimed.

摘要： Methods and systems to detect droop events on-chip, which may include a sensor circuit located adjacent to a voltage node to convert a corresponding voltage to a digital count or value indicative of the voltage. The sensor circuit may include an n-stage ring oscillator and an asynchronous counter. The sensor circuit may include circuitry to capture and convert a phase associated with a count to a binary fractional value to increase voltage resolution. Multiple counts associated with the node may be evaluated at the node to identify minimum and maximum counts and corresponding time stamps. More complex evaluation and control circuitry may be shared amongst a plurality of sensor circuits and may include circuitry to generate and compare counts to one or more variable thresholds, circuitry to average counts over time, and memory to store state values associated with the sensors.
