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.
