Application analysis of high voltage DC power supply

 

1000kW load bank

 

HVDC power supply technology has two main development directions, one is to improve the power supply, that is, high voltage, high current; The second is to reduce the volume of the power supply, namely high voltage, small volume, reducing the volume of the power supply is mainly to improve the switching frequency of the power supply. High power supply volume is generally large, small power supply volume, its power and current will be relatively small. The development direction of HVDC power supply is also high conversion efficiency, high load, high precision and low ripple.

 

HVDC power supply has been widely used in medical, station, customs inspection and other testing equipment, also widely used in radar transmitter, electronic aviation chart display and other military fields. The traditional high voltage power supply has a large volume and heavy weight, which seriously affects the development of supporting equipment. The current HVDC power supply is mostly in the form of switching power supply, which greatly reduces the volume and weight, increases the power and improves the efficiency. In particular, the switching power supply with high voltage and low power is almost the switching power supply structure.
