Abstract

See full text

This disclosure is directed to hybrid continuous and discontinuous mode operation. In general, a system comprising a control module and voltage converter module may be configured to operate in a continuous conduction mode (CCM) until a current through an inductor in the voltage converter module is determined to be at or below zero (e.g., negative). The controller may then transition to operating the voltage converter module in a discontinuous control mode (DCM). Some or all of the DCM may be implemented digitally within the controller. In this manner, benefits may be realized from operating in either CCM or DCM while minimizing the disadvantages associated with these control schemes. Moreover, digitizing DCM control may allow for easier implementation and better performance than traditional DCM operation.
