Audio Power Amplifier with H-Bridge - MATLAB & Simulink
https://www.mathworks.com/help//physmod/sps/ug/audio-power-amplifier-with-h-bridge.html
Audio Power Amplifier with H-Bridge. Open Model. This example shows an H-bridge configuration switching audio power amplifier circuit. Switching audio power amplifiers are more efficient than conventional power amplifiers as switching devices are operating only in the fully-on and fully-off states. This audio power amplifier uses a 1MHz switching frequency and has a PI feedback …

One of the biggest advantages of grounded bridge solutions is a significantly reduced “voltage strain” on the power transistors. This linear concept of a 3-stage Class H switch mode power supply enables the design of extremely efficient high power amplifiers featuring peak output power significantly over 200V and unparalleled audio performance.

I'm still relatively new to tube audio, but I know it's superior! I actually was planning on using 6SN7s to drive some headphones. I bought some Sennheiser HD-555s which I am quite happy with. ... H Bridge Amp looks to be promising. Wonder if there are MosFet H Bridges or 1/2 Bridges made, that are big enough for a power amp ? ...

With a h-bridge I still only get 0 to +12v but since the current direct can be changed I can get the speaker to move in both directions. Would this make the speaker loud or am I complete off bases here.

In its simplest form, a switch-mode amplifier consists of an H-bridge and a load (Figure 1). The H-bridge load includes the speaker impedance and a passive filter. The H-bridge steers current to the speaker, and the LC filter attenuates the switching noise.
System Design Considerations for True Digital Audio …

TDAA audio amplifier technology is a direct PCM-to-PWM converter without feedback; this requires good decoupling and a good power supply. The power supply voltage needs to be regulated because the H-bridge is switching the supply level directly to the outputs via the output reconstruction filter.
What Is an H-Bridge? - Build Electronic Circuits

You normally use it with a microcontroller, such as an Arduino, to control motors. When you can control two motors to go either forward or backward – you can build yourself a robot! H-Bridge concept. Here’s the concept of the H-bridge: A DC motor spins either backward or forward, depending on how you connect the plus and the minus. If you close switch 1 and 4, …
