For the electronic, electrical products powered AC mains; harmonic current is an important EMC test project. The electronic, electrical equipment which are used under low pressure mains network, the power supply voltage is a sine wave, but the current waveform is not surely a sine wave, there may be more or less distortion. Plenty of […]
Electronic, electrical products’ intermittent conduction emission of exceeding standard problems and the countermeasures & Electronic electrical products radiation harassment of exceeding-standards and the countermeasures
Electronic, electrical products’ intermittent conduction emission of exceeding standard problems, and the countermeasures. The intermittent conduction harassment nominal measuring frequency range of home appliance products is 148.5 kHz-30MHz (The actual is 150 KHZ – 30 MHZ). The measurement was done on power terminal, and the click measurement frequency point is: 150kHz、500kHz、1.4MHz、30MHz. The main source of […]
