DC/DC CONVERTER WITH STEP -DOWN STEP -UP CASCADE AND METHOD FOR OPERATING IT |
摘要 |
A DC to DC converter including a buck converter, a boost converter, and a control unit, wherein the control unit is arranged to calculate an error voltage of the buck converter Verr_buck based on a feedback output voltage Vout_FB of the DC to DC converter and a reference voltage of the buck converter Vref_buck, and wherein the control unit is arranged to calculate an error voltage of the boost converter Verr_boost based on the feedback output voltage Vout_FB of the DC to DC converter and a reference voltage of the boost converter Vref_boost, wherein the reference voltage of the boost converter Vref_boost is shifted by an offset Voffset as compared to the reference voltage of the buck converter Vref_buck. |
