Title:
POWER SUPPLY APPARATUS FOR HIGH-VOLTAGE DIRECT-CURRENT ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/043457
Kind Code:
A1
Abstract:
A power supply apparatus for a high-voltage direct-current electronic device replaces a high-voltage transformer with multiple cascaded medium-voltage transformers, and couples a power source at the ground potential to a high-potential electronic device by using a low-cost ground-potential power-frequency/high-frequency power source transformer and by cascading multiple transformers. The transformers are cascaded in structure, and a system requires that the insulation voltage exceeding a power supply source is shared or equally shared by the cascaded multi-level transformers, thereby reducing the insulation level of the transformer, decreasing the costs of the transformer and simplifying the production, and creating conditions for application of a high-voltage direct-current electronic device.
