Abstract
Disclosed is a flat knitting machine power supply device, which comprises an alternating-current input terminal, an AC/DC (converting alternating current into direct current) rectifier filter module, a capacitor, a DC/DC direct current voltage conversion module and an output terminal in sequential electric connection. The capacitor is used for storing electric energy to replace a storage battery as a backup power supply.
Description
Technical field
The utility model relates to the straight-bar machines electric supply installation, the straight-bar machines electric supply installation of backup control data when outage especially can be provided.
Background technology
At present, known straight-bar machines power supply is to be connected by several groups of switch power modules, storage battery, inverter to form.When the externally fed sudden power, give inverter power supply by storage battery, inverter is that switch power module is powered, the snap action that guarantees to cut off the power supply is normally finished, and preserves current data, for incoming call continuation braiding next time is prepared.Because the accumulator cell charging and discharging number of times is limited, make in this way straight-bar machines electric supply installation installation cost and the maintenance cost of use all than higher.
Summary of the invention
Need storage battery to mend the deficiency of powering as the back in order to overcome existing straight-bar machines electric supply installation, the utility model provides a kind of electric supply installation, operate as normal when this electric supply installation can not only externally be powered sudden power, and no longer need storage battery and inverter.
The technical scheme that its technical problem that solves the utility model adopts is: after the AC rectification, except that normal filter capacitor, increase by one group of storage capacitor, utilize the electric energy replacement storage battery and the inverter of its storage to power, reach the purpose of cancellation storage battery and inverter for switch power module.
The beneficial effects of the utility model are, in the time of can externally powering sudden power, only keep power supply by storage capacitor, and are simple in structure, with low cost.
