Abstract: Device driver circuits based on H-bridges can be implemented to provide linear control of the H-bridge, reduce power losses, and reduce certain component size/cost. The driver circuits can use two feedback loops to operate the H-bridge in different regions and to guarantee that current flows through an H-bridge load device, such as a thermoelectric cooler, in only one direction at a given time. The H-bridge driver circuits can remove the possibility of high currents bypassing the load device and thus going directly through the switches on either side of the H-bridge driver. The H-bridge driver circuits also ensure careful control of the current applied to the H-bridge load device. Such driver circuits are particularly useful for controlling the current applied to thermoelectric devices.

On the other hand, low-temperature air flows from the air cleaner into the inter-tank-shell space which has become negative in pressure.

Accordingly, the heat-generating members can be stably cooled while the component number of the cooling system can be decreased.
