Title:
Primary voltage perception and control for a converter
Document Type and Number:
Japanese Patent JP6001658
Kind Code:
B2
Abstract:
A controller for a DC/DC converter can include a first error analog to digital converter (EADC) configured to detect a primary voltage from a secondary side of a transformer and generate a first error signal corresponding to the primary voltage. The first error signal is generated based on a comparison between a first reference voltage and the detected primary voltage. A first accelerator can be configured to process the first error signal and generate a first compensation signal that is a primary voltage variation signal used for feedforward control. A second EADC and a second accelerator can be configured to provide a output voltage feedback control. A compensation signal of the first accelerator can be used to scale the second accelerator output to facilitate fast feedforward control.
