The switch-mode power supply in the AHB2 has a regulation loop that can respond at audio frequencies. This allows the regulation to respond to musical peaks in real time. Peak currents are drawn from the AC line on demand rather than from stored energy in a bank of capacitors. Measuring the Magnetic Emissions of the AHB2
Switching Power Supply - Basic Car Audio Electronics
http://www.bcae1.com/swpowsup.htm
For car audio, amplifiers and high output preamplifiers need more voltage. To boost the voltage, a switching power supply is typically used. The most common type of switching power supply uses a transformerto boost the voltage. A less common method uses diodesand capacitorsin what's commonly referred to as a 'voltage doubler'.

A class D amplifier is a switching power supply. Those are more common these days and can have quite good specs. Audiophools may wrinkle their noses when they are told a amplifier is class D or has a switching power supply inside, but such a thing is harder to detect in a proper double blind test. In the audio world, it can be difficult to separate the science and …

Due to cost and size, the majority of power supplies you’ll see are switch-mode. Taking a look at the low-noise benefits of an LPS, you’ll expect to get better sound from an LPS. This doesn’t mean you can’t get great performance from an SMPS. In fact, some manufacturers have found an LPS to be noisier than SMPS.

2016-05-25. From servers in data centers to telecom equipment and industrial systems, switched-mode power supplies (SMPS) are used in a wide range of applications because of benefits such as high efficiency, power density, and faster transient response at low cost. However, while offering many advantages, SMPS supplies such as switching buck and step-up DC/DC …

This power supply project can supply power to any one channel audio power amplifier project presented in this website. The AC line votage goes into the primary of the power transformer through a fuse and a switch. The AC is then transferred to the secondary winding by magnetic induction to whatever voltage your audio amplifier requires.

The EMI filter stops Rf (radio frequency) switching noise generated by the switch mode power supply from getting back out into the 110V 240V mains system effecting other equipment connected to the mains. There are strict international regulations governing the maximum Rf radio frequency noise that electronic products must comply within.

A switching AC/DC power supply enables the creation of more efficient power converters, which no longer dissipate the excess power. AC/DC power supplies that are designed using switching power converters are called switched-mode power supplies. AC/DC switched-mode power supplies have a slightly more complex method for converting AC power to DC.
