Abstract: Circuits, methods, and systems are directed to controlling the amount and polarity of current to multiple loads with switches, where the loads share switching components. The loads may be thermoelectric elements, which heat o r cool based on the state of the switches. The switches may be run in a sing le mode during a duty cycle, or multiple successive modes during the duty cy cle to achieve full control of the loads.

Abstract translation: 电路，方法和系统旨在通过开关来控制到多个负载的电流的数量和极性，其中负载共享开关元件。 负载可以是基于开关状态的加热或冷却的热电元件。 开关可以在占空比期间以单一模式运行，或者在占空比期间以多个连续模式运行，以实现负载的完全控制。
