Capacitor Coupled Amplifiers

Introduction. In theory, capacitor-coupled output stages are completely straightforward, and there''s no uncertainty about how they work. We all know that a capacitor passes AC and blocks DC, but with a single-supply power amplifier (or any other Class-AB single-supply circuit for that matter), current is only drawn from the power supply with positive half-cycles.

Electrolytic Capacitors in Power Supplies

They may be found in the power factor correction boost stage or as part of the wide input voltage range circuitry for energy storage. Electrolytic capacitors are also common components for filtering on the output of the power supply for low ripple voltage and stability. The specification of the power supply often states the lifetime of these ...
