MULTI-MODE CONTROL FOR A DC-TO-DC CONVERTER

摘要

An apparatus 7900 includes a voltage regulation module 7902 that controls output voltage VOUT of a bidirectional DC-to-DC converter to an output voltage reference VSET over an output current range between a positive power reference PSET and a negative power reference - PSET. A positive power regulation module 7904 controls output power POUT to the positive power reference PSET over a positive constant power range between the output voltage reference VSET and a positive output current reference ISET. A negative power regulation module 7906 controls output power POUT of the converter to the negative power reference -PSET over a constant power range between the output voltage reference VSET and a maximum negative power 10 limit, and a constant current module 7908 limits output current to a positive output current reference ISET in a range between a minimum output voltage and output power of the converter reaching the positive power reference PSET.
