The measurement of drive power, input power, power factor and harmonic There are many ways to use power analysis capabilities of the Tektronix oscilloscope products you can easily achieve these power quality measurements. Channel to measure the input voltage and channel all the way to measure the input current with the oscilloscope’s built-in PWR power analysis software, all power quality parameters can be displayed directly on the screen.
Drive power efficiency of high power gu10 led and power within the switching losses are directly related. Reduce the loss of power devices is not only improved power efficiency, but also a key factor to improve the thermal stability and reliability. However, the switching losses of power device measurement is not easy to achieve. As the device turns on and off state of the voltage amplitude difference between high power gu10 led and led high bay lights in such a large dynamic range can not accurately measure the tiny voltage-state conduction losses is no way of measuring.
For high speed switching power devices, can only be multiplied by the voltage and current transient power approach to computing power. Then the voltage and current must be the same moment of the waveform, otherwise the error is huge. However, the principle and structure of the voltage and current probes for high-speed switching signal time delay. If you can not accurately correct for high power gu10 led, the measurement results of the oscilloscope is not credible. Tektronix oscilloscope power measurement scheme not only has a comprehensive test function of the switching loss, also has a powerful probe calibration function to completely eliminate the time delay error.
