This power supply could power a 555 oscillator driving an LED. Another test used C ac =0.22µF, R1=10kO, R2=470O, R B =470O, C F =470µF, and Q1=BC549. This could be used to build a zener-transistor ...

Isolated power is usually generated with a transformer, but it can also be generated using capacitors. For some systems, the constraints of size and cost may favor capacitors. In Figure 1, the IC ...

SPICE simulations determine power supply decoupling performance. David Bourner, National Semiconductor, Columbia, Md. Noise management, induced by digital circuits on a p. c. board assembly ...

In a switch-snubbing circuit, the capacitor is placed in series with a resistor/diode combination and connected across the power switch—typically an IGBT or MOSFET—to control dV/dt (Fig. 2).

They are two terminal devices that are essentially open circuit all the time an AC voltage is applied, but switch to short-circuit when the ac signal is removed. In conjunction with a series ...
