Debug Power Factor Correction Circuits with a Digital Phosphor Oscilloscope

Most switching power supply designs incorporate active power factor correction circuits to achieve a unity power factor. While this maximizes efficiency, it has also made waveform analysis with a digital oscilloscope cumbersome. Now, however, you can dramatically speed design and debug tasks by using a TDS5000B Series, TDS7054 or TDS7104 digital phosphor oscilloscope (DPO) with TDSPWR3 power measurement and analysis software.
