|HP Series High Power High Voltage DC Power Supply|
|The HP Series power supply is a high-power, high-voltage power supply series. Its power ranges from 5kW to 15kW (single unit) with voltage output from 1KV to 60kV.|
The series is mainly equipped with a standard 19-inch chassis structure for easy integration of high-voltage systems.
The high-power inverter used in the HP series power supply adopts the series resonant inverter designed by our company. The input end is directly installed on the power module with ultra-low loss filter capacitor. The input rectification, filtering and inverter are all integrated and installed onto one radiator.
Air-cooled or water-cooled or oil-cooled and water-cooled would be adopted according to the voltage and power rating to ensure good heat dissipation.
The high voltage transformer uses a distributed rectifier transformer. These characteristics give the series of power supplies very high reliability and extremely low energy storage.
|Block diagram & Principle description|
|The IGBT full bridge inverter and the Series Resonant Tank circuit are the key components in this power supply.|
The series resonant inverter converts input voltage source to a equivalent current source, each pulsing is equivalent to an energy pack, which is sent to output load or output filtering capacitor after HV rectifying.
Different output voltage and current corresponds to different output pulsing frequency, adjusting pulsing frequency leads to output voltage and current changes.
|The HP unit is made up of four different functional parts as shown below:|
Rectifier PartThis stage takes three-phase 380Vac or 440Vac input, then after rectifies and filters, it creates a 600Vdc pulsing DC output.
High Frequency DC/AC PartThis stage uses an IGBT (Insulated Gate Bipolar Transistor) full bridge circuit to convert the pulsing DC to a high frequency AC waveform that feeds the next stage.
Series Resonant Tank PartThis part is an inductor in series with a capacitor. This LC network defines the characteristic impedance of the system and the frequency at which the AC current resonant.
High Voltage AC/DC PartThis part uses a transformer to step up the high frequency AC the necessary high voltage level. A rectifier circuit is then used to convert the high voltage, high frequency AC to the high voltage DC.
