ABSTRACT:
A series drive circuit for driving a plurality of serially-connected electronic elements, such as electrochromic elements. The series drive circuit maintains a accurately controlled voltage across each of the electronic elements, while reducing power consumption and current consumption. A constant voltage is applied to the serially-connected electronic elements that is the sum of the required voltage for each of the electronic elements. In order to prevent excess voltage across any of the elements, shunts are connected in parallel with each of the elements. In order to reduce excess voltage across any of the elements, the voltage across each of the elements is monitored and used to control the shunts to maintain a accurately controlled voltage across each of the serially-connected electronic elements.
