  • Is It Time To Take A Serious Look At Convection Cooled Switched Mode Rectifier/Chargers Again
    Switched Mode Rectifier/chargers (SMR's) are the dominant method of stationary battery charging for telecommunications, information technology (IT) and other standby power application. The vast majority of these are forced air cooled. In North America, the exception is with the utility companies
  • Thyristor and Rectifier Testing Using Curve Tracers
    electronics such as power supplies, amplifiers, and variable input and output functions that allow the user to display the operating characteristics of a device in an easy-to-read, standard graph form. Operation of Tektronix CTs is simple and straightforward and easily taught to non-technical
  • The Good Old Power Resistors
    of high-voltage power transformers could put you to sleep. If a current needed "tweaking" you looked at a 3-inch panel meter, and took control with a knob you could get your whole fist around!
  • The `Good Old` Power Days (.pdf)
    of high-voltage power transformers could put you to sleep. If a current needed "tweaking" you looked at a 3-inch panel meter, and took control with a knob you could get your whole fist around!. Power resistors were big wirewound guys. They had hollow cores and were covered with shiny brown enamel
  • AN1106, Power Factor Correction in Power Conversion Applications Using the dsPIC (R) DSC
    , IN POWER AND CONTROL SYSTEMSa rectifier with a capacitive filter is necessary. However, this results in discontinuous and short duration current To understand PF, it is important to know that power spikes. When this type of current is drawn from the has two components: mains supply, the resulting
  • 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
  • What You Need to Know About SCR Power Controllers
    Temperature regulation is required in nearly every manufacturing process, typically for the purposes. of material heating, melting, drying, or forming. SCR power controllers, also called silicon controlled rectifiers (SCRs), play a critical role in temperature regulation. Their primary use
  • Watlow SCR Power Controllers and Ohio Semitronics Watt Transducers
    , with many different industrial applications occurring, including the control of heaters, ovens, and furnaces that incorporate Watlow (R) power control equipment. When specifying a PC5 model to use with a Watlow DIN-A-MITE (R) SCR (Silicon Controlled Rectifier), there are questions to consider in order
  • Low Inrush Transformers
    Custom Transformers Three Phase Transformers Single Phase Transformers Single Phase Open Frame Control Transformers Three Phase Open Frame Transformers Rectifier Power Transformers High Frequency, Ferrite Cored, Transformers & Chokes Valve Audio Transformers Variable Transformers Chokes / Inductors
