Abstract: In a rotary electrical machine control apparatus, a selection section selects a relay current limiting value or a coil current limiting value depending on whether a plurality of systems are operated or one or more but not all of the plurality of systems are operated. The system is a combination of a winding set, an inverter, and a power supply relay, which correspond to each other. The relay current limiting value is a current limiting value calculated based on the temperature of the power supply relay. The coil current limiting value is a current limiting value calculated based on the temperature of a choke coil.

Abstract: Techniques for AC input signal detection, whereby a method for AC input signal detection may include: sampling an input signal at a sampling rate, where the input signal is based on an AC signal; comparing the input signal with a threshold signal, determining a first value in case the input signal is larger than the threshold signal; determining at least one second value in case the input signal is smaller than the threshold signal; increasing the sampling rate in case a predefined number of consecutive first values is determined; and decreasing the sampling rate in case the at least one second value is determined.

Abstract: A voltage detection circuit includes two detection capacitors, which are paired and configured differentially, first to third detection switches, a drive part, a minimum selector and a maximum selector. The first detection switch is formed of a pMOS transistor, which opens and closes a path between one of the detection capacitors and an input node. The second detection switch is formed of an nMOS transistor, which opens and closes a path between the other of the detection capacitors and an input node. The third detection switch is formed of a series circuit of a pMOS transistor and an nMOS transistor, which open and close a path between two detection capacitors. The driving part turns on and off complementarily between the first and second switches and the third detection switch. The minimum selector applies a lower one of voltages of the input nodes as a substrate potential of the nMOS transistor. The maximum selector applies a higher one of the voltages of the input nodes as a substrate potential of the pMOS transistor.

Abstract: An improved measurement system may include a source measure unit (SMU) capable of performing accurate low-level current measurements. Based on an SMU design that provides a controlled DC voltage source with precision current limiting and a controlled 0V (zero Volt) DC at the measurement terminal, an AC design may be implemented to establish the same (or very similar) conditions over a specified frequency range. Instead of controlling each digital-to-analog converter (DAC) at respective source terminals of the SMU as a respective DC output, each DAC may be controlled as a respective function generator with programmable frequency and continuously variable phase and amplitude. Off-the-shelf pipelined analog-to-digital converters (ADCs) may be used to monitor voltage, current and the voltage at the measurement terminal, and a Fourier transform may be used to obtain both the amplitude and relative phase measurements to be provided to respective control loops.

Abstract: To accurately detect the presence or absence of a signal. A signal detector includes an input-signal amplifying circuit, a reference-signal amplifying circuit, and a comparator. In the signal detector, the input-signal amplifying circuit amplifies an input signal with a predetermined gain. The reference-signal amplifying circuit amplifies a reference signal at a constant signal-level with a gain that substantially matches the predetermined gain. The comparator compares a signal level of the amplified input signal with a signal level of the amplified reference signal, and outputs the comparison result as a detection signal.
