High Voltage Converter

HIGH VOLTAGE DC CONVERTER

Advantages of the resonance switching technology

The high voltage DC converter (DC-DC converter) from our German supplier Iseg Spezialelektronik GmbH ranges from 100 V up to 30 kV. The DC-DC converter is based on a patented resonance switching topology. This is particularly suitable for high voltage applications for the following reasons.

  • the waves cut by the transistors are not rectangular but sinusoidal.
  • the zero crossing of the sinus induces an automatic and stress-free switching of the transistors (soft switching).
  • the natural protection of the transistors and the primary of the transformer against short-circuits is done with its resonant circuit LC opposing fast 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.

The constraints existing in conventional topologies (forward, flyback) are nonexistent here. It contributes to decrease the stress level on the components. They improve stability and contribute to a very significant increase in the reliability of our converters.

1 W to 150 W HV DC converter

We offer our converters for a very wide range of applications:

High voltage DC ‘print module’ converter for PCB

The smal high DC converter to be soldered on PCB circuit using square pins is articulated around the APS, BPS and CPS-Mini ranges which offer powers of 0.5 W, 1 W, 3 W, 4 W and up to at 8 W.

Very low noise and high stability high voltage DC converter

The DC converter type DPS and DPS-Mini is more advanced, with powers from 5 W to 12 W. It offers a very high level of stability. It is used in advanced applications which require extremely low levels of ripple & noise as well as very good stability over time. The DPS type DC converter (sometimes called DPR with R = reversible) offers electronic polarity switching by high and low TTL signal.

High power high voltage DC converter

The high voltage DC type CPS (12 W) and EPS (60 W and 150 W) converter of the third and last line is more suitable for use with high voltages and high currents.

High voltage DC converter for PMT tubes

The PHQ model DC converter is tailor-made for projects that use photomultiplier tubes (PMT). Operating voltage up to 3 kV DC.

DC-DC converter used in high-voltage instrumented power supplies

High voltage DC converter of the DPS, DPS-Mini, CPS and EPS series is designed to be integrated in a desktop power supplies (THQ Desktop) and industrial rack power supplies (THQ Rack). In this case, the high voltage converter is enriched with local instrumentation around multi-turn potentiometers and LCD displays to control voltages and currents.
