Class H Amplifier

Class H Amplifier

This project aims to develop a lower-cost Class H amplifier design that can be used not only for audio, but other applications as well with little-to-no modification required. The design is based around a class AB amplifier like many reference designs. Open source designs are uncommon and not well documented for this class of amplifier and commercial designs are expensive. This amplifier design will include clear documentation to allow for easy replicability and modification. Key specifications and their impact on performance have been researched and were used to guide the design process. The design has been broken up into sections and most have been successfully simulated.

About

Open Source Hardware specializes in building low-cost alternatives to expensive hardware/software, and then sharing the designs with the commons so that collaborative improvements can be made rapidly. Anyone can make changes or updates to the designs the Enterprise team creates—through this process, designs are improved at a much higher rate than would be possible within the Enterprise alone. Open source is all about collaboration.
