What is a high-power DC power supply? A high-power DC power supply is an indispensable device for various electronic devices. Its function affects the overall performance of the product. The choice of power supply depends on the product's performance and requirements. A high-power DC power supply can effectively power high-power devices.
Advantages of High-Power DC Power Supplies
High-power DC power supplies meet users' needs for high-current, high-voltage DC power, and have unique advantages in voltage and current stabilization. They feature high efficiency, high reliability, flexibility, high stability, environmental adaptability, and modular design. They can improve production efficiency, reduce energy consumption, support new technologies, and are very convenient to use.
Applications of High-Power DC Power Supplies
High-power DC power supplies are used in many fields, such as: providing stable power to various motors and control equipment in industrial automation; power transmission and distribution in power systems, and as emergency power; providing precise voltage and current control for various experimental equipment in scientific research; providing stable power to base station equipment in the communications field to ensure communication continuity; and providing fast charging services in electric vehicle charging stations.
High-Power DC Power Supply Testing Methods
To ensure a newly purchased high-power DC power supply has all the necessary functions and that its input and output are working correctly, we need to test it. So how do we test it? Here are some suggestions:
The technical specifications of a high-power DC power supply fall into two categories: characteristic specifications, including input and output voltage, output current, and the allowable adjustment range of the output voltage; and qualitative measurements of output DC voltage stability, including voltage stability coefficient (or voltage correction), output resistance (or current correction), texture voltage (ambient and random drift), and temperature coefficient.
1. Texture Voltage: The AC component applied to the output voltage. The peak reading on an oscilloscope is usually in millivolts. The actual value can also be measured on an AC millimeter voltmeter, but since it's not a sine wave, there will be errors. The total power adjustable DC voltage VP-P&LE: 10MV.
2. Voltage Stability Coefficient: The relative change in input voltage that causes a relative change in output voltage under load DC and ambient temperature.
3. Voltage Regulation Rate: ±10% of the relative change in input voltage; the relative change in output voltage at 10%. Since the voltage regulation coefficient and voltage regulation speed represent the effect of input voltage changes on the output voltage, only one of them needs to be checked.
4. Output Resistance and Current Regulation
The output resistance is equal to the amplifier's output resistance, and its value is the absolute value of the ratio of output voltage to output current under constant input voltage.
5. Current Regulation: The relative change in output voltage as the output current transitions from zero to its maximum value. You only need to check one section, whether it's the output or the current regulation, depending on how changes in load current affect the output.
Summary
High-power DC power supplies are indispensable devices in various electronic devices. They possess characteristics such as high efficiency, high reliability, flexibility, high stability, environmental adaptability, and modular design, and are widely used in industrial, scientific research, and communication fields. Testing a high-power DC power supply can be done by checking aspects such as trace voltage, voltage stability coefficient, and voltage regulation rate.
