Function of isolation voltage of buck module power supply(1)

HVDC module power supply
High-power switching high-voltage DC power supplies are widely used in large-scale equipment such as electrostatic dust removal, water quality improvement, medical X-ray machines and CT machines. The voltage is as high as 50~159kV, the current reaches more than 0.5A, and the power can reach 100kW.
Since the 1970s, some Japanese companies have begun to use inverter technology to rectify the mains and invert it to an intermediate frequency of about 3kHz, and then boost it. In the 1980s, high-frequency switching power supply technology developed rapidly. Siemens of Germany uses power transistors as the main switching elements to increase the switching frequency of the power supply to above 20kHz. And the dry-type transformer technology is successfully applied to the high-frequency high-voltage power supply, the high-voltage transformer oil tank is cancelled, and the volume of the transformer system is further reduced.

buck power supply 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 buck power supply supply, dcdc power module, acdc power supply supply, high voltage input power module, customized buck power supply supply, 3W/10W/25w/75w/100W/200W and other dcdc power supply 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.
