Abstract
A power supply has a power factor correction (PFC) circuit and a DC to DC conversion circuit. A DC to DC controller of the DC to DC conversion circuit acquires zero-crossing information and load information from the PFC circuit through a communication protocol, and performs a low-frequency compensation on a control command using a table-mapping means, thereby resolving the issues of higher controller complexity, changes of entire response characteristics and cost increase in conventional compensation technique.
