Jie Shengda Technology DC-DC converter detection method

                         Jie Shengda Technology DC-DC converter detection method
   When the DC-DC converter used in the actual unit circuit,its electrical performance is very important,Which related to the stability of equipment and instrumentation So we have to rigorously teste the DC-DC converter to ensure it is qualified before using in the whole system, equipment, instrumentation power supply or voltage conversion.
DC-DC converter test methods and test equipment required as follows:DC-DC high-voltage module , AC-DC converter testing method in principle is identical, here not introduced .
1、Adopting a standard Kelvin four-terminal  testing method:

The consists of testing equipment:
a、DC adjustable regulated power supply: Input voltage range of the equipment is large enough
b、ammeter (A): The instrument measurement accuracy requirements is 0.001
c、voltmeter (V): This instrument requires precision is 0.001
d、load resistance: rated load (U * U / P) that the output voltage square divided by the power, light load (10 * U * U / P)
e、connecting wires : line losses as small as possible so as to avoid excessive pressure-drop
