Charging power supplies
CHG-3000
Features: - Fast charging of capacitors - Signalling of the end of charging - Signalling of system damage - Resistance against output shorting - Resistance against lack of loading
The CHG - 3000 is a construction designed to charge the main capacitors of solid-state lasers pumped using a flashlamp. The system is a full - bridge converter operating in the resonance mode. The modern fast technologies of IGBT transistors have been used in the system together with specialized integrated circuits. This construction ensures high energetic efficiency and reliability of the power supply. The system is resistant to shorting and break in the output circuit and fluctuations of mains voltage in the specified range. The charger does not have its own auxiliary power supply and must be connected to such a 24 [V] power supply. However, this is not a problem as the majority of system subassemblies is supplied from 24 [V] source and such a power supply is included in the electrical system of the laser. A single charger provides 3.0 [kW] power. In case of need the chargers can be connected in parallel, which enables to multiply the output power of the system. A standard version of the charger gives the maximum voltage up to 1200 [V]. There is also a possibility to prepare other voltage versions by special order.

CPS-3000 The most modern type of power supply designed for complex servicing of the pulsed laser. In accordance with the current trends in this field, the power supply includes the charger, simmer, auxiliary 24 [V]/10 [A] power supply, and, which is the most important, the corrector of the power factor. The charger is contained in a compact casing provided with suitable couplings and terminals as well as fastening holes. The device is resistant to shorting and breaks in the input circuits and to interference. The converters operating in the device are made on the basis of the IGBT and MOS - FET technologies. These are the circuits that operate in a full bridge resonance mode, which ensures high efficiency.
