Driving power supply device of parallel connection expansion high-power all-solid-state laser

Abstract

The invention discloses a constant current driving power supply of a high-power all-solid-state laser, wherein a parallel connection expansion technology is adopted in the constant current driving power supply. The driving power supply comprises a primary power supply module, a plurality of same secondary power supply modules, an auxiliary power supply module, a current setting and display module and a start / stop control module, wherein the primary power supply module is connected with the secondary power supply modules in parallel to equally share the total load currents, and the secondary power supply modules are controlled by the primary power supply module. According to the driving power supply, the parallel expansion technology is adopted, several low-power switching power supply modules are connected in parallel to form the high-power driving power supply, and driving of the high-power all-solid-state laser can be simply and reliably achieved.

Description

technical field [0001] The invention relates to the technical field of solid-state laser driving power supply, in particular to a parallel expansion high-power all-solid-state laser driving power supply device. Background technique [0002] High-power all-solid-state lasers are widely used in the fields of information industry, laser processing, national defense industry, laser weapons and tactical equipment, but high-power lasers often require a higher-power drive power supply to provide them with operating current. At present, the common all-solid-state laser drive power supply adopts the switching power supply technology of PWM control mode. The switching power supply has the advantages of high efficiency, small size, and large input voltage range. However, the power switching device and transformer core required by the high-power switching power supply, It is difficult to choose, and the difficulty of circuit design increases with the increase of power. At the same time,...

Problems solved by technology

[0003] The driving source of all solid-state lasers is an adjustable constant current source, and the current common switching power supply parallel technology is generally designed for constant voltage sources. A small number of constant current power supply parallel solutions are designed for specific applications and do not have output current. Continuously adjustable function, so it is not suitable for driving power of all solid-state lasers
