H Bridge Amplifier. A class d amplifier using this h bridge has the potential of providing kilowatts of audio power see the sidebar on bridge power. Suppose you re asked to design a power amplifier with two performance goals.
Class d amplifier terminology and differential vs. In particular a bipolar stepper motor is almost invariably driven by a motor controller. There is a trade off however.
These circuits are often used in robotics and other applications to allow dc motors to run forwards or backwards.
This is more commonly used with ic power amplifiers where it is desired to have a system capable of generating large power into the rated load impedance i e the load impedance used is the one specified for a single amplifier. An improved h bridge power amplifier for controllably driving a dc motor is presented. The h bridge configuration is ideal for driving dc and stepper motors. Figure 3 shows a differential implementation of the output transistors and lc filter in a class d amplifier.
