Bipolar high power DC-DC converters

The Bi-Polar C series line of regulated DC-to-DC high voltage converters from Ultravolt is an extension to the company's high power C series. These units contain a pair of + and - standard product 60 or 125 W high power C series assemblies providing a total of 125 or 250 W. By encapsulating a module pair within one case, the cost of testing, potting, burn-in and system integration is reduced, says the manufacturer.
The ± HV output pair is packaged into Ultravolt's 114 x 203 x 28 mm standard case. This high power density is especially suited to high-energy pulsers, amplifiers and discharge devices with large capacitance, fast repetition rates or high current loads. The bi-polar C series matches the standard Ultravolt 60/125 W high power C series for all electrical functions and design methodology including: wide input range, remote control, enable/disable, output monitors and local +5 V d.c. reference output.
Output range is adjustable independently from 0 to ±125, ±250, ±500, ±1 kV, ±2 kV, ±4 kV or ±6 kV on all 60 W x 2 and 125 W x 2 models. As the output voltage is reduced towards 0, the maximum current capability remains unchanged. Internal capacitance is kept to a minimum to facilitate fast rise applications. Most fast rise applications involve charging a storage capacitor, which also acts as an additional output filter/storage capacitor. If the application is continuous DC bias power, an external filter/storage capacitor should be added.
