Electronic Project of Laser Power Supply

Here is Electronic Project of optical maser Power offer circuit, ICl may be a 555 timer running at concerning sixteen kilocycle per second. This IC drives Ql, a TIP146, that produces a 12-V sq. wave across atomic number 81 primary. This produces between 800 and a couple of,000 V across the secondary, that is doubled to three to five kilovolt.

Laser Power Supply Circuit Diagram:

When the load (laser) on the power supply increases, current Q2 is turned on, which energizes RY1. This changes the duty cycle of the 555 timer, lb adjust this supply, set R12 and R13 at the center. Adjust R12 until the laser tube triggers, and make sure that the relay pulls in. If the relay chatters, adjust R12. If the full-clockwise adjustment of R12 fails to ignite the tube, adjust R13.
