1.1 Switch-Mode Amplifier Review Switch-mode amplifiers operate by using the output power devices as switches. Power amplification is accomplished by modulating the switching duty cycle of semiconductors (or vacuum tubes) as they alternate between high conduction and off states. Subtle differences in topology and how the switches are modulated ...

\$\begingroup\$ You can build extremely large, high-power amplifiers without switch-mode power supplies, by employing a many-tap mains transformer, and doing rail-switching. You can get similar efficiencies to SMPS designs, albeit at the cost of a massive 50/60Hz power transformer. \$\endgroup\$

Switching Supply in the AHB2 Power Amplifier. The AHB2 is a linear power amplifier with switch-mode power supplies. To the best of our knowledge, it has the highest SNR of any audio power amplifier. The A-weighted SNR is 132 dB in stereo mode and 135 dB in mono mode. This is 15 to 30 dB better than most of the best power amplifiers.

SMPS – PS Audio

Switch Mode Power Supplies, or SMPS, just sounds nasty. No, not the supply itself but the word “Switch Mode”. Shades of choppy, digital, not linear, radiating, messy. Definitely something you want to stay away from. A SMPS is a linear power supply only it doesn’t have a big power transformer like what we think of when we mention a linear ...
