  • An Analysis of Current-Source Inverters Using High-Frequency WBG Switches
    For several decades, MOS-gated power devices have been the prevalent choice for voltage-source inverters (VSIs) and current-source inverters (CSIs) in machine drives. However, recent advancements in power semiconductor technology, specifically the development of wide bandgap (WBG) power
  • AN-0100 - Using a VMI Opto-coupler in Conjunction with High Voltage Relays
    This application is for use in a scanning electron microscope, which has different operating. modes. In one mode, a large negative voltage (nominally -10kV) must be applied to an. electrode. In the other mode, a small voltage must be applied, but with a high current. capability. In both cases
  • Silicon Carbide Semiconductor Devices at Ultra-high Voltages and their Applications
    ) and high voltage direct current transmission (HVDC). To further improve efficiency in terms of performance and keeping in mind the overall cost of the device, silicon carbide (SiC) is the new trend in the field of electronics.
  • Common Mode Field Rejection in Coreless Hall-Effect Current Sensor ICs
    Allegro current sensor ICs use the Hall-effect to measure the magnetic field produced by an integrated, current carrying loop, translating the magnetic field to a voltage which is proportional to the current flow. This technology has many advantages, including galvanic isolation, low power loss
  • Amplifying High-Impedence Sensors ? Photodiode Example
    of sensors, used to sense events in the real world. They can be R R F N classified according to the role they play in the analog V OUT conditioning circuitry, such as voltage source, current I C S - Csource, resistive and capacitive (frequency-based). S N This application note discusses the analog
  • Designing Atmospheric-Pressure Plasma Sources for Surface Engineering of Nanomaterials
    within the. sample channel, making DEP more appealing for mass. production. iDEP relies on a direct current (DC) voltage, or. low-frequency alternating current (AC) voltage, applied. across the sample channel, where insulating structures. within the microfluidic channel create the electric field
  • High-Speed Lithium Ion Battery Charger
    Driven by the need for untethered mobility and ease of use, many systems rely on rechargeable batteries as their primary power source. The battery charger is typically implemented using a fixed-function IC to control the charging current/voltage profile. The C8051F300 family provides a flexible
  • Why Consider Ceramic Feedthroughs
    Ceramic feedthroughs are ceramic-to-metal fabrications that are utilized to transmit electrical signals, high currents/gases/fluids, or high voltages from between external sources to a hermetically-sealed chamber.
