  • AC vs DC Power in Data Centers and Wiring Closets
    AC vs DC in Data Centers and Wiring Closest. Which is more cost effective for you?. Proponents of DC Power argue that the use of DC Input equipment provides the opportunity for conversion into one central large AC-to-DC converter thereby cutting down on heat loss and increasing efficiency
  • Thermal Considerations For DC/DC Converters
    All power converters - AC/DC, DC/DC and DC/AC - consume power that is dissipated internally as heat. This heat must be removed from the power-dissipating component in the converter in order to keep its functioning temperature low and other critical components at relatively low constant temperatures
  • Diagnosis of a DC to Three Phase Power Converter
    The customer needs to make a special converter that converts DC voltage from a high-efficiency battery to 3 phase AC and they are trying to optimize converter efficiency.
  • Methods To Increase The Hold-Up Time Of AC/DC Or DC/DC Converters
    Microprocessor-based systems monitor their own power supplies to start or terminate operation. A so-called 'watchdog” circuit continuously monitors and informs the processor of the condition of its supply voltage. Figure 1 displays a typical TURN ON/OFF timing diagram of a converter and watchdog
  • Key Considerations for PFC Conductors
    PFC (Power Factor Correction) inductors are used in active boost circuits to correct harmonic current distortion in AC to DC converters. The goal is to achieve a Power Factor (PF) as close to 1.0 are possible.
  • Using Regenerative Converter Units to Recover Over Voltage Energy in AC Drive Systems (.pdf)
    Regeneration occurs in an AC variable frequency drive system when the load overhauls the motor. This can occur when trying to decelerate the load, or when some external force causes the motor to overhaul, causing the motor to act like a generator. The energy contained in the rotating equipment
  • Driving the Analog Inputs of a SAR A/D Converter
    the impact of an operational amplifier on the analog-to-digital conversion in terms of DC as well as ac responses. A typical system block diagram of the SAR converter application is shown in Figure 1. Some common SAR converter systems are Data Acquisition Systems, Transducers Sensing Circuits, Battery
  • Using Economical SocketPac (R) Removable Terminal Carriers to Mount Power Converters on PCBs Speeds Assembly, Saves Energy, and Simplifies Repair (.pdf)
    High-value printed circuit boards (PCBs), used in applications such as mainframe computers, automatic test equipment, industrial control systems, and telecommunications systems, frequently incorporate single or multiple AC/DC or DC/DC converters, power supplies and battery packs. During assembly
