摘要
A multi-output DC-DC converter that can optimize its cross-regulation performance is proposed, in which a nonlinear inductive element functioning as a leakage inductance of an output coupled inductor is placed on the output channel of at least one secondary circuit coupled to a secondary winding of a transformer. The inductance of the nonlinear inductive element is varied in inverse proportion with the variation of the current flowing through the nonlinear inductive element. When the load on an output end of the DC-DC converter is changed, the output channel having a higher load current is configured to produce a lower leakage inductance and the output channel having a lower load current is configured to produce a higher leakage inductance, and thereby balance the output currents flowing through the output channels of the DC-DC converter.
