  • Comparing the Maximum Voltage of Brush DC and BLDC Motors
    The maximum voltage capabilities of brush DC and brushless DC (BLDC) motors are fundamentally different, which is primarily due to each motor technology's specific design and operating principles. In brush DC motors, physical brushes conduct the electrical current, which limits their maximum
  • Performing Low Voltage Continuity Tests With High Voltage Hipot Testers
    in two models. The 7620 is an AC Hipot, and the 7650 is an AC/DC/IR tester. The HypotULTRA III has two separate Continuity test modes. The first test mode allows the operator to perform a simultaneous Ground Continuity Test with a 1 ohm maximum limit along with the Hipot test. This method of continuity
  • Sensorless Brushless DC Motor Control with PIC16
    the many advantages to a BLDC motor no speed regulation. over a brushed DC motor, we can enumerate the following: HARDWARE * The absence of the mechanical commutator The hardware for a BLDC system can be decomposedallows higher speeds into the following sections: * Brush performance limits
  • Application Note: Output Inductor Selection for the AAT115X Series Buck Converter
    . AnalogicTech's AAT115X switch mode buck converters require that the output inductor ripple current be limited to 30% to 40% of the rated current at the maximum input voltage (Eq. 1). This limits the peak switch current while still providing a good ramp slope for the PWM peak current mode comparator
  • Power supplies for the next generation of CompactPCI systems
    In order to supply the components of the system with their required DC voltages, power. supply units (PSUs) are built into CompactPCI systems. The tasks of the PSUs include the. following: to provide a secure galvanic isolation from the public mains, to reduce and rectify. the voltage and to smooth
  • Achieve up to 99% Efficiency in a Robust Battery Backup System Using a True Bidirectional Buck-Boost Controller
    and according to the current health of the battery. With its inherent nature of true peak current sensing and ability to limit the average current, the high-voltage buck-boost family of products from Renesas Electronics provides a comprehensive solution for battery-powered and battery backup
  • Design and Development of Medical Electronic Instrumentation
    signals. Projects include a dc-coupled biopotential. amplifier with automatic offset cancellation, biopotential amplifier with dc rejection,. ac-coupled biopotential amplifier front end, bootstrapped ac-coupled biopotential amplifier,. biopotential amplifier with selectable RC bandpass filters
  • Glass vs. Metal CO2 Laser Tubes
    cooling system also presents some significant safety concerns. The DC power supplies that excite the CO2 gas in a glass laser tube need to operate at very high voltages. When you combine such levels of voltage with a water cooling system, the results can be lethal should something go wrong
