This brief derives the efficiency limitations of switched capacitor power amplifiers (SCPAs) due to switched capacitor (SC) losses during charging and discharging of their capacitor arrays. Polar ...

Energy-storage devices called capacitors deliver power rapidly, but the amount of energy they can absorb is limited. Deliberately disordered electric dipoles in ‘antiferroelectric’ capacitor ...

Step 1: Identify the capacitor’s leads Capacitors usually have two leads – one positive (longer) and one negative (shorter). In some cases, capacitors may be marked with a + or – sign, or indicate ...

Discover the most effective solutions for protecting car batteries from reverse polarity and how smart diode controllers can play a significant role in making that happen.

One of the main reasons of metal film capacitors failure in pulse modes is a degradation of contacts between film metallization and solid electrodes-contact edges. This paper presents the results of ...

Ever wonder what’s inside an electrolytic capacitor? Many of us don’t, having had at least a partial glimpse inside after failure of the cap due to old age or crossed polarity. The rest of us ...

As most of you will be able to confirm, an electrolytic capacitor has to be connected the right way around in an electronic circuit. If you get the connections wrong, the innards of the capacitor will ...
