Class H Amplifier

Class H Amplifier. ClassH amplifiers create an infinitely variable (analog) supply rail They are sometimes referred to as rail trackers This is done by modulating the supply rails so that the rails are only a few volts larger than the output signal “tracking” it at any given time.

The class H amplifier can actually be thought of as two amplifiers in series In the schematic example shown by the figure + 40 V rail amplifiers can produce about 100 Watts continuous into an 8 ohm load If vout music signal is operating below 40 volts the amplifier only has the losses associated with a 100 W amplifier.

Amplifier Classes C to H Learn About Electronics

Of course as amplifier manufacturers try to push the envelope of power delivery with amplifiers like the 1000 watt Emotiva XPR1 MonoBlock they turn to Class G/H and Class D designs to avoid having their amplifiers double as space heaters Meanwhile on the other end of the market are Class A aficionados who can forgive a lack of efficiency in the hopes of purer.

ClassH A similar (at least in some respects) arrangement is called ClassH and it can be difficult to decide exactly into which camp some amplifiers fall ClassH is often described as using a ‘bootstrap’ capacitor that lifts the rails as needed but cannot maintain them at the full voltage for more than a few cycles.
