slovakia Noise test method of voltage boost power supply module(6)


It is a method to measure the output ripple voltage of  voltage boost power supply module by using 50 Ω coaxial cable. The coaxial cable is directly connected to the oscilloscope. To reduce noise, an aluminum or copper grounding plate shall be used during measurement. The measured value is 1 / 2 of the actual value


●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.

AC/DC Module power

It is another measurement method using double lines.
