Abstract
Disclosed are a charge and discharge balancing circuit and an LED drive system, which include multiple charge and discharge branches, each of which includes a charge circuit and a discharge circuit. The charge and discharge branches are each connected to an energy storage device. The charge circuits are connected to a charging power supply, and the discharge circuits are connected to a load. Each charge and discharge branch determines whether to charge the connected energy storage device according to a voltage signal of the charging power supply and a voltage signal of the connected energy storage device, and determines whether to discharge to the connected load according to a voltage signal at a load connection terminal and the voltage signal of the connected energy storage device. The voltage signal at the load connection terminal is the maximum value among the voltages transmitted to the load by each branch.
