  • Brushless DC Motor Control Using PIC18FXX31 MCUs
    A PICDEM TM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage
  • Hybrids
    ceramic substrate to efficiently conduct heat to the ambient. Common configurations include single-phase half-wave bridges that often contain a freewheeling diode for inductive loads, switches for single and three-phase ac switching applications, and SCR doubles for single and three-phase bridges
  • Phase Control Using Thyristors (.pdf)
    parallel may be used. One of two methods may be used for full-wave DC control - a bridge rectifier formed by two SCRs or an SCR placed in series with a diode bridge as shown in Figure AN1003.1.
  • Differential VCO Design for GSM Handset Applications
    will attempt to build a. bridge toward better understanding of the differential VCO by. describing a design covering 910-980 MHz which is appropriate. for use in GSM handsets. This design will also demonstrate how. the SMV1493-079 varactor diode, an essential element in this. VCO, may be used
  • Stopping the Flow of Counterfeit Components
    billion in revenue to counterfeiters annually. And that doesn't include indirect effects such as the costs of field service, recalls, and warranty claims as well as the harm to product image and customer satisfaction. Affected components run the gamut from integrated circuits, transistors, diodes
