System and method for starting up a high-density isolated DC-DC power converter

摘要

A DC-DC power converter has a transformer gate with a primary side and a secondary side and a primary circuit electrically coupled to the primary side of the transformer. The primary circuit includes a primary microcontroller configured to generate a first excitation signal that energizes a portion of the primary circuit. The DC-DC power converter also has a secondary circuit electrically coupled to the secondary side of the transformer. The secondary circuit includes a secondary microcontroller communicatively coupled to the primary microcontroller, wherein the secondary microcontroller is configured to provide a command to the primary microcontroller that causes the primary microcontroller to control the primary circuit to the secondary Microcontroller transmits, and wherein the secondary microcontroller is further configured so that it provides a second excitation signal for the part of the primary circuit.
