Buying a high-voltage power supply (buy in Russia) that fully meets the requirements of the equipment being designed is often a difficult task for engineers, developers and physicists who do not have much experience in power electronics. This problem became especially acute after the introduction of economic sanctions against Russia, for the reason that the main suppliers of high-quality high-voltage equipment for many years were American (Spellman, Ultravolt, AdvancedEnergy) and Japanese companies (Matsusada, Hamamatsu).

In this series of articles, the authors set the task of acquainting Russian equipment manufacturers with high-voltage power supplies, high-voltage solid-state switches and high-voltage pulse generators produced by the domestic company PARAMERUS LLC, to help navigate this science-intensive and high-tech industry of Power Electronics.

High-voltage power supplies, general overview and classification is the topic of the first article in the cycle.

Ensuring high-quality power supply in the 21st century is a basic task in the development and production of almost any equipment, this issue is especially acute for instrument makers of analytical, testing, radar equipment, as well as optical systems that use high-voltage power supplies.

A high-voltage power supply, depending on the application, is evaluated by such critical parameters as output voltage ripple, efficiency, transient rate, EMI, temperature and time instability, and error.

In 2019, PARAMERUS LLC was registered in the Russian Federation, which set itself an ambitious goal - within 5 years to eliminate the misunderstanding that Russian developers depend on high-voltage power supplies of foreign production and provide the domestic market with high-voltage power supplies that will, at least no worse than Western counterparts, both in terms of technical characteristics and in terms of industrial performance. All developed products were designed taking into account the requirements of the EU, US and China markets, and the products are positioned not only as import-substitution-oriented, but primarily as export-oriented.

As of August 2022, PARAMERUS LLC has mastered and launched into industrial production high-voltage power supplies with power from 0.5 W to 4 kW, voltage from 125 V to 60 kV.

High-voltage power supplies manufactured by PARAMERUS can be conditionally divided into low-power/small-sized, intended for mounting on a frame or soldering on a printed circuit board, with 12V or 24V input power, and stationary, designed for installation in a server rack or on a laboratory table, with power from the mains 220V or 380V.

The model range of small-sized high-voltage power supplies is graphically presented in Fig. 1:

Fig. 1 Model range

HVULP is a series of ultra-compact high-voltage power supplies up to 2 W, voltage up to 1.5 kV designed to power PMTs. Also, these power supplies can be used as reference voltage sources in equipment where high functionality is not required, direct monitoring of output parameters and overall dimensions are important. dimensions.

HVLP is a series of compact high-voltage power supplies with power from 1W to 8W, voltage from 250V to 6kV. The housings are made of high quality plastic, with a metal housing available as an option. Complete input and output protection, <0.05% ripple, excellent stability, accuracy and dynamic performance (Picture.3)

HVMP is a series of high-voltage power supplies with power from 10W to 50W, voltage from 250V to 40kV. The power supplies of this series have two case versions: for models up to 8 kV and for models from 10 kV to 40 kV. Ripple <0.01%, stability and accuracy of setting the output parameters allow you to use the most important analytical and test equipment (Picture. 4)

HVHP is a series of high-voltage power supplies with a capacity of 65W, 125W and 250W, voltage from 125V to 30kV. The units in the standard version have an output ripple of less than 1% and can be used both to form a stable high voltage DC and to work on an impulse load. The highest efficiency in its class on the world market (up to 92%) allows the use of a plastic housing and does not require any special cooling when operating with ambient temperatures up to +55⁰ (Picture. 5)

The plastic material of the housings complies with UL94-V0 requirements, does not deform under vacuum, and has excellent insulating and heat transfer characteristics. Filling with a compound is carried out in a vacuum environment, which eliminates the appearance of voids and the formation of bubbles during hardening.

To select a high-voltage block for the task, to help coordinate the system with the high-voltage cascade, to ensure the stability of the output characteristics of high-voltage pulse devices - all these and many other problems go away from equipment developers in cooperation with the specialists of PARAMERUS LLC.
