H Bridge Amplifier. The tch1560 pelteir h bridge provides both positive and negative polarity control of pelteir modules via its heat and cool inputs. 1 create a 10v peak to peak voltage swing and 2 drive both positive and negative polarities.

There is a trade off however. In particular a bipolar stepper motor is almost invariably driven by a motor controller. An improved h bridge power amplifier for controllably driving a dc motor is presented.
Bridging an amplifier combines the available channels into one channel with half the ohm ω.
The h bridge configuration is ideal for driving dc and stepper motors. Bridging an amplifier combines the available channels into one channel with half the ohm ω. The motor is connected in the center of the h bridge in conventional manner. Figure 3 shows a differential implementation of the output transistors and lc filter in a class d amplifier.
