Powerful 2000W Power Amplifier Class-H

Class H Powerful amplifier circuit 2000W
Class H is an analog amplifier which aims to improve the efficiency of the amplifier B / AB class. In class B / AB, the supply voltage is only one pair which is often denoted as + VCC and -VEE for example + 24V and -24V (or written with +/- 24volt). In class H amplifiers, the supply voltage is multilevel. Especially for applications that require high voltage power, so that the supply voltage is efficient, there are 2 or 3 different pairs. For example, there is a supply voltage of +/- 154 volts, +/- 77 volts and +/- 12volt. For example, for soft and low sound, the active pair is +/- 77 volt supply voltage. Then if it is necessary to drive a loud sound, the supply voltage can be switched to a maximum supply voltage pair of +/- 154 volts.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


cannot down load pdf, has error in rar file

Try it again, what the size of rar file that you downloaded

Its rar format you must extract file before you can open the pdf file
