The resonance switching topology and its advantages
The DC high voltage power supply from our German partner Iseg Spezialelektronik GmbH is based on the resonance switching technique.
- the waves switched by the transistors are not rectangular (like forward or flyback topology) but sinusoidal,
- the zero crossing of the sinus wave induces an automatic and stress-free switching of the transistors (Soft switching on Mosfet and IGBT),
- the natural protection of the transistors and the primary of the transformer against short-circuits is done with its resonant circuit LC opposing quick variations in current,
- the high frequency harmonics are greatly reduced due to the sine wave close to the fundamental, thus reducing the level of ripple & noise at the output and EMI interferences.

DC and isolated power supply for filament
In addition to the HPS power supply, the FPS (Filament Power Supply) series is a dedicated power supply for filaments, often used in electron beam applications (for example EB-PVD).
The main advantage is to combine it with any high voltage power supply on the market in order to connect an insulated filament.
The FPS therefore has a high voltage input connector and a high voltage filament output connector. Power from 30 W to 600 W. The FPS filament floating power supply is available in 19’’- 2U rack. Together with our partner Iseg we perform the integration of the filament into the high voltage power supply.
Filament wiring and insulation
The filament is isolated from the earth with insulation voltages from 5 kV to 75 kV depending on the model. The FILAMENT point (-) is brought to the hot spot of the high voltage power supply while the FILAMENT point (+) delivers the filament tension.
Very high precision DC high voltage power supply
The SHQ model is the top of the range in its category, with the best specifications in terms of ripple & noise, stability in regulation, resolution, precision, drift in time and temperature. With its 2 current measurement ranges which are switched automatically, it offers a resolution as fine as 100 pA for an accuracy of 2 nA. These performances make the SHQ model a tool dedicated to the characterization of high sensitivity detectors such as Germanium, Silicon, Gaseous, etc.
Reversible, high-precision DC high-voltage power supply
The SHR high-voltage power supply is the latest addition to Iseg’s high-precision range. The polarities (positive / negative) are electronically switchable. The other performances (ripple & noise, quality of regulation, resolution, precision, drift over time, drift in temperature, etc.) are identical to those of the SHQ range. With its 2 current measurement ranges which are automatically switched, it offers a resolution as fine as 50 pA for an accuracy of 4 nA. These performances guarantee the best equipment on the market for the characterization of detectors in the fields of nuclear and particle physics.
Configurable high voltage DC power supply
The THQ HV PS model is a ‘kit’ formula, assembled from small DC / DC converters.
- Equipped with CPS and EPS ‘Standard’ high voltage converters of 12 and 60 W, the performance of the THQ will suit Electrospinning applications or polarizations and tests of power components.
- Equipped with the DPS ‘High Stability’ high voltage converter, the criteria of reverse polarity, low noise and advantageous stability will give complete satisfaction in R & D applications.
The THQ power supply is a very good price / quality compromise offering good technical guarantees. THQ power supply is offered:
- In compact table format, with 1 or 2 independent high voltage channels, it is suitable for research laboratories.
- In 19” rack format with 1, 2 and 3 channels. In this case, the space offered by the rack makes it possible to increase the powers up to 60 W per channel and even 150 W.
