High voltage DC power units with energy recovery
Heinzinger provides high precision DC power units for applications in the area of battery substitute. Over the years, these power units are advancing more and more in test beds of hybrid motors as well as electrical components of the future in the automotive and supplier industry. The power units can then be equipped with energy recovery, which makes a significant contribution to cost reduction when operating. Heinzinger accommodates for these requirements with the new PTNer unit series. The devices, as doubly stabilised, linearly-regulated power units, satisfy surpassing demands in terms of precision and stability. With these high precision power units, precision classes between 0.001% and 0.01% are achieved. The devices are combined with the "Heinzinger energy recovery" system for energy recovery. Particular attention is paid to realising the changeover between power unit and energy recovery operation with these new power units capable of energy recovery. In order to enable an automatic test process, special intelligence on the part of the power unit is necessary. For this, the power unit system independently recognises which operational state the connected "consumer" is in. The important thing here is whether the "consumer" is requiring or recovering energy. This detection takes place rapidly and with a minimum tolerance threshold.
Examples
There are now four devices series available as HighPrecision Version (hp): The unit series will be presented to the expert public at the elctronica 2006. The devices of the hp series are available in the low-voltage range as PTNhp and in the high-voltage range as further developments of the reliable PNC and PHN unit series as PNChp and PHNhp. For lesser output the HNCEhp are available.
Devices in High Precision
New High Voltage Power Supplies:
Heinzinger MRC series, 2.1 kW high voltage power supplies in various voltage ratings up to 100,000 V. The power supplies act as multi-resonance converters. This technology allows a highly compact unit design and pricing which also permits employment of the high voltage power supplies in price sensitive applications.
