Currently, the two main types of high-power DC power supplies used for testing are: linear DC regulated power supplies and high-frequency DC power supplies.
Linear DC voltage and current stabilizing power supplies employ linear series and silicon-controlled rectifier (SCR) adjustment modes, featuring high accuracy, high stability, low ripple coefficient, and high anti-interference capabilities. They are primarily used by research institutions, laboratories, and electronic production lines for testing high-precision DC voltage and current stabilizing power supplies. High-frequency DC power supplies, utilizing IGBT module adjustment modes, offer high efficiency, precision, and stability. They are mainly used by research institutions, laboratories, and electronic production lines for power testing. Aviation power supply.
The control chip for the DC regulated power supply utilizes mature imported components, while the power components are made with newly developed high-power devices internationally. The design of the adjustable DC regulated power supply eliminates the bulky and heavy nature of traditional DC power supplies due to the use of industrial frequency transformers. Compared to traditional power supplies, the high-frequency DC power supply offers advantages such as smaller size, lighter weight, and higher efficiency. It also facilitates the reduction in size of high-power DC power supplies, and is also known as a high-frequency adjustable switching power supply. The adjustable DC regulated power supply is equipped with comprehensive protection features, allowing for continuous setting of overvoltage and overcurrent points with preview capabilities. The output voltage can be controlled via a touch switch.
Technical specifications for high-power DC power supplies can be divided into two main categories: one is characteristic specifications, which reflect the inherent characteristics of the DC voltage regulator, such as input voltage, output voltage, output current, and output voltage adjustment range; the other is quality specifications, which reflect the quality of the DC voltage regulator, including stability, equivalent series resistance (output resistance), ripple voltage, and temperature coefficient. 400HZ power supply
