Title:
HIGH POWER FACTOR POWER CONVERTERS WITH ADAPTIVE OUTPUT VOLTAGE LIMITS FOR FAST DYNAMIC LOAD RESPONSE
Document Type and Number:
WIPO Patent Application WO/2017/004816
Kind Code:
A1
Abstract:
A switching power converter is provided that switches between low-bandwidth PI control and a high-speed control of an output voltage responsive to comparing the output voltage to an upper output voltage limit and to a lower output voltage limit. The switching power converter adapts the upper and lower voltage limits responsive to a load demand.
