BI-DIRECTIONAL CURRENT SOURCE

摘要

A bi-directional current circuit disposed between two power sources (106, 107) and a load (108). A first switch (110) and a second switch (112) each connect the load to one of the power sources respectively, whereby when the first switch is closed and the second switch is open current flows to the load in a first direction and when the first switch is open and the second switch is closed current flows to the load in a second direction opposite to the first direction.
