  • Driving AC-DC power supply efficiency even higher
    : This 250W AC/DC power supply is up to 95% efficient. A feedback loop monitors the power supply output and varies. the boost converter voltage, which in turn varies the voltage at. From the outset achieving high efficiency was the primary design. the input to the main converters. The primary purpose
  • Methods To Increase The Hold-Up Time Of AC/DC Or DC/DC Converters
    . Application Note DC-007. dyne. DC/DC CONVERTERS. Methods to Increase the Hold-up Time of AC/DC or DC/DC Converters. Microprocessor-based systems monitor their own. soft start phase. The soft start time can be anywhere from. power supplies to start or terminate operation. A so-called. one millisecond
  • How to Reduce Size and Increase Performance in AC-DC Power Supply Design
    Improvements in AC/DC power supply design are evolutionary, rather than revolutionary. It's easy to settle for tried-and-tested approaches because no one new design technique is likely to yield great benefits. The design challenge is to establish what small enhancements can be made in various parts

Regeneration occurs in an AC variable frequency drive system when the load overhauls. the motor. This can occur when
  • Controlling 3-Phase AC Induction Motors Using the PIC18F4431
    than the PIC18F452 or PIC16F7X7. Practically speaking, control of a 3-phase AC induction motor requires pulse-width modulated control of the six switches of a 3-phase inverter bridge connected to the motor's stator windings (Figure 1). The six switches form 3 pairs of "half-bridges", which can
  • Shrinking to the Challenge - How to design a Smaller, More Efficient AC-DC Power Supply
    functionality needed for a standby converter. The standby converter provides an. independent 5V output whenever AC power is present. Today's best-in-class AC/DC switchers are typified by XP Power's EMA212 power supply, shown in Figure 2. Using some the. techniques described above, this packs 212.5 W output
