Abstract
The invention provides a novel super capacitor charging method and device, and belongs to the technical field of medical instruments. The device comprises a charging control circuit 1, a super capacitor set 2 and a sampling circuit 3. An inductor L1 and an inductor L2 are used for limiting currents, the inductor L1 is in serial connection with the inductor L2, on-off states of a main return circuit are controlled through a silicon controlled rectifier D2, and a silicon controlled rectifier D1 makes the inductor L2 short-circuited when voltage of the super capacitor set 2 rises to 2/3 of a rated value, so currents of the main return circuit are controlled under 8A. The charging method includes the steps that the sampling circuit 3 tracks changes of the voltage of the super capacitor set 2 and the changes of the voltage of the super capacitor set 2 are set to the charging control circuit 1; the charging control circuit 1 has a comparator U1A and a comparator U1B, R1, R5 and R6 are set so that output of the U1A can change from a low level to a high level when the voltage of the super capacitor set rises to 2/3 of the rated value, the silicon controlled rectifier D1 is communicated with the short-circuited inductor L2, and output of the U1B changes from a high level to a low level when the voltage of the super capacitor set 2 rises to rated voltage, so the silicon controlled rectifier D2 is stopped, and charging of the super capacitor set is stopped.
Description
Technical field
The invention belongs to technical field of medical instruments.
Background technology
Because the vast capacity of super capacitor makes that the powered on moment electric current is huge, for the electrical injuries equipment that prevents that this is huge, must limit the charging current of super capacitor.Many based on the Switching Power Supply charger at present, its shortcoming is that circuit is comparatively complicated, and cost is higher, and this super capacitor charging device circuit of existing invention is simple, cost is low, dependable performance, is specially adapted to X-ray machine inside and charges to super capacitor.
Summary of the invention
