Abstract
The invention discloses a novel supercapacitor charging method and apparatus. The apparatus is composed of three parts, i.e., a charging control circuit 1, a supercapacitor set 2 and a sampling circuit 3. Inductors L1 and L2 are used for limiting currents, the inductors L1 and L2 are connected in series, controlled silicon D2 is used for controlling conduction and disconnection of a main loop, controlled silicon D1 is used for performing a short circuit on the inductor L2 when the voltages of the supercapacitor set 2 rise to two thirds of a rated value so as to control the currents of the main loop to be 8A below. The specific circuit is as follows: the sampling circuit 3 is used for tracking the voltage change of the supercapacitor set 2 for sending to the charging control circuit 1 then. There are two comparators U1A and U1B in the charging control circuit 1. When the voltages of the supercapacitor set are enabled to rise to two thirds of the rated value through setting an R1, an R5 and an R6, the output of the comparator U1A jumps to high level from low level, and the controlled silicon D1 is enabled to be conducted to perform the short circuit on the inductor L2. When the voltages of the supercapacitor set rise to the rated value, the output of the comparator U1B jumps from high level to low level, and the controlled silicon D2 is enabled to be cut off to stop charging supercapacitors.
