  • Using AC PWM Drives on Non-Standard Voltages and Frequencies
    Often, there may arise the need to apply an AC PWM drive1 to input voltages such as 200, 208, 380, 415 and possibly other levels, as well as input frequencies such as 50 Hz. The AC PWM regulator utilizes a switching power supply for control power that is sourced from a DC bus. This gives the unit
  • Technical Notes for Power Suppies
    Regulated DC voltage is required for semiconductor devices such. as ICs and Transistors to function. Regulated voltage can be generated. from commercial AC lines with an AC to DC power supply or. from DC power source (such as Batteries) with a DC to DC converter. Each type is further classified
  • The lowdown on lowdropout regulators
    Voltage regulators that maintain output control almost to the supply rail operate cooler and increase efficiency. Low-dropout regulators like this MCP1726 from Microchip Technology create a self-contained power regulator for embedded microprocessors. The MCP1726 maintains regulation within 150 mV
  • Power-Supply Fundamentals
    of chemistries. Modern power supplies typically use solid-state rectifiers for converting ac line voltage to some desired value of dc. The dc output voltage may be unregulated or regulated to any degree of precision and stability. Power supplies have different filter arrangements for eliminating ac
