Abstract |
This paper proposal presents a new high power Class-D audio amplifier for woofer applications. A regulated DC voltage supply is not needed as well as a low pass output filter overcoming the disadvantages of ordinary audio amplifiers structures. A 1kW laboratory prototype was implemented and it was found that a 94\% efficiency and 1\% of THD could be achieved. A detailed design guide line, principle of operation analysis, control strategy, is also included in this paper proposal. |
