The number and types of electrical devices in modern society are increasing. Inside each device, there is generally a voltage conversion device that converts the power supply from the external power supply or the built-in battery into the voltage required by the internal circuit board. These voltage conversion devices are power supplies. According to the input source, there are generally two types of power supplies on the market: one is an AC-DC power supply, which converts AC mains power into low-voltage DC power, such as mobile phone chargers, computer adapters, etc.; the other is a DC-DC power supply, which isolates and stabilizes the DC output of the AC/DC power supply or battery or further reduces the voltage, such as DC-DC module power supply, L7812 step-down chip, etc.
However, for some special equipment or applications, ordinary power supplies cannot meet the requirements and require special high-voltage output DC-DC power supplies. Next, let's learn about the application scenarios of DC-DC high-voltage output power modules?
Remote power supply
The distance between the power supply and the load is far, such as hundreds of meters or thousands of meters. At this time, the line loss voltage drop may be several volts to tens of volts. If the power supply is directly supplied, the voltage at the load end may drop to an unbearable level. First, raise the power supply voltage by hundreds or even hundreds of volts. Under the same power transmission conditions, the voltage drop caused by long-distance transmission accounts for a low proportion. Add an ordinary step-down power supply to the input end of the load to get the required voltage.
Industrial automation field
Automated production line: On industrial automation production lines, many devices require high-voltage direct current to drive motors, solenoid valves and other actuators. The DC-DC high-voltage output power supply module can convert the low-voltage power supply of the factory into the required high-voltage direct current, providing a reliable power source for the production line. It can also realize the isolation and voltage stabilization functions of the power supply to protect the equipment from grid fluctuations and interference.
Robotics: The control system and drive system of the robot usually require power supplies of different voltage levels. The DC-DC high-voltage output power supply module can provide high-voltage DC power for the robot's motor driver and provide a stable low-voltage power supply for the control system. This helps improve the performance and reliability of the robot.
Below is a power supply with high-voltage output, IPS-350-V4S24U-S. This product meets the requirements of the ultra-wide high input voltage range of 300-1500VDC, with an output power of up to 350W, and has multiple protection functions such as input reverse connection protection and output overcurrent/short circuit protection. Moreover, this is a high-power 350W small-volume natural heat dissipation high-voltage power supply module, which is easy to carry.
There are many occasions for applying high-voltage output power supplies, such as the high-voltage generator used in medical X-ray equipment, which generates 30-150kV DC high voltage electricity, excites the X-ray tube, and emits X-rays. Ultrasonic flaw detectors, photomultiplier tubes, avalanche diodes, solid-state detectors, EO lenses, piezoelectric devices and other equipment in the production and testing fields may all use DC high-voltage power supplies.
