Design of class-D amplifier for subwoofer
Brázda, Jakub ; Petržela, Jiří (referee) ; Brančík, Lubomír (advisor)
This work is focused on design high performance D class amplifier for subwoofer. The type of amplifiers and their parameters are described. The next part of work is design of preamplifier with active low-pass filter. Preamplifier enable set dividing frequency, phase and volume. The switching power supply of forvard topology id design for a both devices. The design od all part is supported by calculations and simulations. For every device is design PCB. The appearance of device is designed so that it can be placed into the speaker box.
