Power supply

A power supply for an audio amplifier has a sub-audio frequency-switched power filter between both poles of a DC input and both respective poles of a DC output. A capacitor is charged from the supply and then discharged into the load. Continuous power may be supplied to the load with two capacitors...

Zusammenfassung:	A power supply for an audio amplifier has a sub-audio frequency-switched power filter between both poles of a DC input and both respective poles of a DC output. A capacitor is charged from the supply and then discharged into the load. Continuous power may be supplied to the load with two capacitors C1, C2 alternately switched so that one capacitor charges whilst the other supplies the load. Therefore there is no direct connection between the power supply and load, preventing audio signals reaching the load, and also preventing signals generated by the load circuit from reaching the dc input. The power supply is suitable for use in an aircraft.
