apacitors and FiltersImproving power quality for efficiency and reliabilityCapacitors are needed in the different parts of the etwork as part of reactive power compensation an
Too often we get / give the advice to replace all electrolytic capacitors on a PCB when it starts to malfunction (like in DVD player power supply circuit strange behavior. Need help to understand root cause but here are many more examples). Reason seems to be the huge difference in quality for these capacitors.
ess inspection of element windingConsideration to the environment is a givenOne of the primary functions of a capacitor - generating reactive power in order to lower he losses in the network - is in itself an environmentally friendly function. Anyway, all development work at ABB is oriented towards creating environm
You also need to know that the application isn't over-stressing the capacitor. A bad design that leads to excess ripple current or operating temperature or excessive voltage (or some combination of the three) may cause even the best capacitors on the market to fail prematurely.
