Solutions for the Power Testing Industry<\/p>\n\n\n\n

<\/p>\n\n\n\n

Power supply is an important part of electronic equipment, from small cell phones, media players in the power supply, to a variety of power drive and energy conversion equipment, the core of the electrical<\/p>\n\n\n\n

Regulatory changes and distribution of energy. The development, design and commissioning of these power supply devices requires a wide range of electronic test instruments.<\/p>\n<\/div><\/div>\n\n\n\n

Power Device Testing<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Power semiconductor devices are the core devices for energy conversion, whether they are MOSFETs or IGBTs, they all bear the important responsibility of power adjustment. The loss of the power device itself is an important factor affecting the overall efficiency of the power supply, high loss will lead to device heating and may affect the life of the power supply. Oscilloscopes generally use instantaneous power integration to measure the loss waveforms of power devices, and RIGOL oscilloscopes support power testing, with a full range of high-voltage differential and current probes to meet a variety of testing needs, and the PC version of the UltraPowerAnalysis software can export the test data, complete a variety of parameters of the on-line and off-line testing, and generate reports.<\/p>\n<\/div>

Ripple analysis<\/strong><\/h2>\n\n\n\n

Power supply ripple is an important parameter for evaluating DC power supply, which consists of industrial frequency ripple, switching ripple and high frequency noise. Accurate testing of ripple requires that the ripple of the test instrument itself be as small as possible, and that the test system have minimal impact on the test results. one of the key features of RIGOL oscilloscopes is the low noise floor, and one of the oscilloscopes, the DS2000A, can provide industry-leading vertical sensitivity of 500uV\/div, which is very suitable for testing power supply ripple and such small signals. pvp2150\/pvp2350 The PVP2150\/PVP2350 probes provide two attenuation ratios of 1:1\/10:1, and 1X can provide a bandwidth of up to 35MHz, which can be directly used for ripple testing.UltraPowerAnalysis software provides a ripple analysis function module.<\/p>\n\n\n\n

modulation analysis<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

In order to improve the efficiency of the power supply, most of the switching power supply can be used in the power factor can be adjusted FPC circuit, gate drive pulse adjustable. In the frequency drive system, bipolar PWM drive pulse is also needed to simulate, test and verify the RIGOL arbitrary waveform generator can produce a variety of pulse width modulation signals, dual-channel output, the channel is completely isolated, especially suitable for simulation of various types of drive signals. The measurement trend plotting function of the oscilloscope can analyze the change rule of the modulating signal.<\/p>\n<\/div>

Production and Aging Test<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Power supply products need to complete a large number of rapid parameter testing and aging test, these tests must be simultaneous multi-channel parameter measurement and recording function. For test results that exceed the limits, the system needs to be alarmed. All of these needs can be easily accomplished with the RIGOL M300 data acquisition system. 6 1\/2 digit meter test accuracy, test speeds up to 250CH\/s and system configuration capability of up to 320 channels make the M300 an ideal tool for production testing and temperature, humidity and aging testing. The large display and PC software make setting up and using the M300 a breeze.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>
