  • Optimize Power Factor Correction Inductors
    have a power factor of 1.0. Circuits containing inductive or capacitive elements have a power factor below 1.0. For two circuits utilizing the same amount of real power, the system with the lower power factor will have higher circulating currents due to energy that returns to the source from energy
  • Dimming Power LEDs Using a SEPIC Converter and MCP1631 PIC Attach PWM Controller (.pdf)
    Programmable Current Source Reference Design. A Microchip MCP1631 PWM controller and a low-cost PIC16F616 microcontroller are used to manage a SEPIC (Single Ended Primary Inductive Converter) powertrain. The SEPIC topology is then used to drive and dim Light Emitting Diodes (LEDs). Dimming Power LED
  • High Power IR LED Driver Using the PIC16C781/782
    discharged the system is idle until the. start of the next pulse. A side benefit of using an inductive energy transfer. from the battery to the LEDs is that variations in the bat-. tery voltage have little effect on the energy transferred,. because the charge cycle is held until the inductor cur

    regularly timed basis with a suitably equipped remote location, such as a nurses' station. MICS is set to completely replace magnetic-inductive coupling techniques, thereby providing faster data transfer and longer range in pacemaker and defibrillator applications. Magnetic-inductive coupling supports
  • Wireless Sensor Connections
    . Slip rings wear and can introduce electrical noise into the system, while connectors offer alignment problems and contact failures. One method circumvents these problems by replacing the physical electrical connection with one that's inductively coupled. A wireless inductive system transfers power
