[0002] For the quality inspection of general electrical finished products or parts, because the test requirements stipulated by relevant laws and regulations increase year by year, in order to find out the critically defective UUTs, when traditional power output devices are generally used for testing, no matter in terms of power consumption, heat loss and volume Both of them increase in equal proportions, relatively affecting the reliability and stability of the equipment, which in turn affects the reliability of the test results, and does not meet the new trend requirements of energy and environmental protection.

[0003] like figure 1 and figure 2 As shown, with the high-voltage and high-current measuring equipment in the prior art for the high-voltage and high-current measurement of the object under test, the traditional power output stage outputs a high voltage of 500W (5000V, 100mA, 60Hz) and its total power consumption can be as high as 1400W, which includes up to 900W heat loss; then output high current 180W (30A, 6V, 60Hz) continuous work with traditional power output stage, the total power consumption can be as high as 530W, including up to 350W heat loss

[0004] When the above test is carried out with high voltage and high current at the same time, when the output high voltage 500W (5000V, 100mA, 60Hz) and high current 180W (30A, 6V, 60Hz) work continuously, the output of the traditional power output stage needs to consume about 1930W, of which Heat loss up to 1250W, the traditional electrical socket can no longer bear the load, must use a special socket

And because there is 1250W power consumption in the test equipment, the test equipment needs forced ventilation, relatively large heat dissipation system and increased weight
