Function of isolation voltage of non-isolated power supply(2)

Power Active Filter
When the traditional alternating current-direct current (AC-DC) converter is put into operation, a large amount of harmonic current will be injected into the power grid, which will cause harmonic loss and interference. For example, when uncontrollable rectification is added with capacitor filtering, the third harmonic content on the grid side can reach (70~80)%, and the power factor on the grid side is only 0.5~0.6.

non-isolated power supply are used in different places, and the matching specifications do not need to be selected. For example, AD-DC power supply is isolated. Generally, the isolation breakdown voltage specified in manufacturing sites is 5000VAC to 6000VAC; Generally, the manufacturing sites of dcdc power modules specify 1500VDC to 2500VDC, which will be higher in special manufacturing industries, and 6000VDC is specified in the medical device industry. Zhuo Xuan Electronic Technology is a professional manufacturer of non-isolated power supply, dcdc power module, acdc dc power supply module supply, high voltage input power module, customized non-isolated power supply, 3W/10W/25w/75w/100W/200W and other dcdc dc power supply module supply, which can provide a stable and reliable controller voltage for the customer system, and reasonably alleviate the problem of good and bad power use caused by static electricity and surge. It is also a data collection Expected plan for common power of communication subsystem.
