3. Output power: 5KW/10KW/15KW
4. Output voltage & current both 0 ~ 100% rated value continuously adjustable.
5. CV & CC working modes
6. Max. charging/discharging repetition frequency: 50kHz
7. Charging/discharging repetition accuracy:  <2% (@50Hz)
8. Forced air cooling, very rugged design
9. Remote control (analog signal or RS port) (optional)


Principle description
The HP unit is made up of four different functional parts as shown below: 

Rectifier Part
This stage takes three-phase 380Vac or 440Vac input, then after rectifies and filters, it creates a 600Vdc pulsing DC output.
 
High Frequency DC/AC Part
This 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 Part
This 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 Part
This 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
 
Theory of Operation
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.

Storage

Pay attention to the following points during temporary & long-term storage.
1. Store the power supply in our packing box
2. Long-term storage would lead to electrolytic capacitor degradation, it should be powered up yearly, at least 5 hours power-on time, input voltage should be increased to rated value by voltage regulator.
