WebMar 16, 2024 · artmaster547 said: ok thank I think the clarifies so a class D amplifier can be implemented using a half bridge or full bridge but not every half bridge structure is a class D amplifier. Yes. Class D amplification is a specific application for a bridge circuit. Class D just means that an AC signal is being generated by a switching amplifier. WebAug 23, 2024 · Given two different Class D amplifier power stage topologies: half bridge (2 FETs) with bipolar power supplies (say +-24V, output switch node is GND-centered) Full bridge (4 FETs) with unipolar power supply (+24V, each of the two output switch notes are +12V-centered) Both of these power stages have maximum theoretical output of …
