  1. Circuits Supply Power Vishay BYV26C BYV28-50 IRFP450 UF5406
    A simple high-voltage MOSFET inverter solves the problem of driving a high-side MOSFET, using a low-voltage transistor, Q 1 , and a special arrangement involving D 6 (Figure 1). This inverter is much faster than those that optocouplers drive, so ...

  1. A few years ago, I worked at a disk-drive company. We had a plating facility that required square waves to drive the high-voltage plating operation. The challenge was that the square wave's pulse width had to be variable, along with the duty ...

  3. Circuits Supply NXP MC68HC908QT1
    Rechargeable nickel-cadmium (NiCd) batteries are widely used in consumer electronics because of their high energy density, long life, and low self-discharge rate. Standard NiCd cells can be charged at different rates: a fast charge with high ...

  4. Circuits Measurement Diodes DMMT3906W MMBT3904 MMBT3906
    You can achieve accurate resistance-temperature-detector sensor measurements without having to resort to using a precision current source. Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision ...

  5. Figure 1a shows the classic implementation of an integrator. The circuit has two properties that may be undesirable in same applications: It necessarily inverts, and it requires a split-supply or midsupply reference. Figure 1b shows an ...

  6. A “swamp cooler” is an easy way to obtain effective air conditioning, especially in hot and dry climates, if a water source is readily available. Although most units are very reliable, the storage-reservoir control usually uses a single ...
