  • Transformer Design for Charging Defibrillator Capacitors
    Generating high voltage by means of flyback topology is a common approach. Using the generated voltage to charge a capacitor for a high energy pulse are used in defibrillators, photoflashs, strobes and ignition circuits to name a few. The procedure outlined in this article is useful in the initial
  • Capacitor Charging and Discharging
    to a circuit whose power supply is DC (DC), there are two processes under certain circumstances, namely the "charging" and "discharging" of the capacitor.
  • Determination of Capacitor life as a function of operating voltage and temperature
    It. has been. assumed that the rate of this wear. -. out mechanism is. directly related to the. leakage current in the capacitor. This means that the relative age of a. capacitor is. proport. ional to the quantity of charge. passed as leakage current. If one knows what. quantity of charge
  • Applying the TC1219/TC1220 Inverting Charge Pumps with Small External Capacitor Values
    Microchip Technology Inc.'s TC1219 (switching frequency at 12 kHz) and TC1220 (switching frequency at 35 kHz) are inverting charge pump voltage converters that are specified using rather large capacitors (10 µF for the TC1219 and 3.3 µF for the TC1220). These capacitor sizes allow the designer
  • Decoupling Capacitors
    Decoupling capacitor is also called uncoupling. The circuit always contained driver and load. If the load capacitance is large, drive circuit should charge and discharge the capacitor to accomplish the transition of signal, when the rising edge is steep, the current is high, so drive current
  • Why does a Capacitor Breakdown
    The electric field strength of the dielectric of the capacitor has a certain limit. When the bound charge breaks away from the bondage of atoms or molecules and participates in conduction, the insulation performance is destroyed. This phenomenon is called dielectric breakdown. The condition
  • Hybrid (R) Capacitor Applications
    Hybrid (R) capacitors have a lower time constant than other electrochemical capacitors. The. behavior of Hybrid (R) capacitors was evaluated in two applications combining high-rate discharge,. limited charging time and current, and high energy density as critical requirements. Capacitance. vs
  • The Role of Electrolytic Capacitors
    Turn the sawtooth wave after rectification into a smooth pulsating wave, which is close to DC. In the power circuit, the rectifier circuit turns the AC into a pulsating DC, and a larger capacity electrolytic capacitor is connected after the rectifier circuit. Using its charge and discharge
