  • Patent number: 10819215
    Abstract: Many DC applications switching converter modules are multilevel, series connected converters. If an individual converter cell fails, it is desirable to be able to bypass the failed cell, in order to continue operating the rest of the converter. A bypass switch is provided as a hybrid switch, including a parallel combination of a slow mechanical switch with high current conduction capability and a low power semiconductor switch with faster acting switching capabilities. When the bypass switch is activated (closed), the low power semiconductor switch is turned on first and quickly establishes the bypass within 10 ?s or less, to temporarily conduct required current until the slower mechanical switch turns on. The mechanical switch is subsequently turned on with zero voltage, given the parallel-connected semiconductor switch being on. If desired, the semiconductor switch can then be turned off with zero voltage, given the presence of the mechanical switch.

    Abstract: A power tool has a tool holder, an electric motor, a handle, and a main switch for switching on the electric motor. The power tool executes the following control method. The main switch is scanned to see whether it has been actuated. A start inhibitor transmits a blocking signal to a motor controller if the main switch is actuated before the power tool has been connected to the power supply. An activator receives signals from a control unit separate from the electric power tool, compares the received signals with a predefined signature and transmits a release signal to the motor controller if the received signal corresponds to the predefined signature. The motor controller switches on the electric motor in response to actuation of the main switch if the start inhibitor is not transmitting a blocking signal or the activator is transmitting a release signal.

    Abstract: A power supply unit for use with thermostats or other like devices requiring power. A power supply unit may be designed to keep electromagnetic interference emissions at a minimum, particularly at a level that does not violate governmental regulations.

Power for triggering may come from a storage source rather than line power to reduce emissions on the power line. Power for the storage source may be provided with power stealing. Power stealing may require switching transistors which can generate emissions. Gate signals to the transistors may be especially shaped to keep emissions from transistor switching at a minimum.

  • Patent number: 10381926
    Abstract: A digitally compensated hysteretic power supply with enhanced resolution is provided. Such a power supply includes a comparator that is used to compare a load current sense signal with an internal signal generated from a digital-to-analog converter (DAC). A compensation circuit at a DAC input operates to improve current accuracy beyond the given DAC resolution. The current sense signal is converted to its digital equivalent, which is fed to a proportional-integral (PI) compensation loop, which in turn generates a relatively precise high resolution DAC input value. The DAC uses the higher part of the DAC value. The lower part of the DAC value is treated as a duty cycle number, and the DAC output is toggled between two levels at this duty cycle. This toggling generates a current output signal having a value that is the average of the two toggled values.

While the external compensation circuit is performing data compensation to the respective sub-pixels in the display area of the organic electroluminescence display panel, the display area of the organic electroluminescence display panel is powered using the power management chip at high conversion efficiency to thereby achieve low power consumption in the data compensation stage.

  • Patent number: 10312822
    Abstract: An electrical system includes a sensing arrangement coupled to an electrical grid interface to measure an electrical characteristic of the electrical grid interface, a power conversion module having an output coupled to the electrical grid interface, and a control module coupled to the sensing arrangement and the power conversion module. The control module determines a reference value for the electrical characteristic, identifies an islanding condition based on a difference between a value for the electrical characteristic and the reference value, determines a target output value for the power conversion module based on the difference, and in response to the islanding condition, operates the power conversion module to provide the target output value for the electrical characteristic at the output. The target output value reduces the difference while a connection arrangement is being opened to achieve islanding.

  • Patent number: 10236881
    Abstract: An input device includes a first component with an actuating layer and a first electrode arranged adjacent thereto, a second component with a carrier and a second electrode, and a device which electrically contacts the first and second electrodes. The first and second electrodes face each other with an air gap therebetween. The first electrode, under an influence of an actuating force acting on the actuating surface undergoes, upon an actuation, a displacement so as to move the first electrode closer to the second electrode against an elastic restoring force. A detection and evaluation device applies a measuring capacitance to the first and second electrodes and detects a change in the measuring capacitance dependent on the displacement moving the first and second electrodes closer to each other in order to associate the actuation with a switching or controlling function after detecting a predetermined change in the measuring capacitance.
