Systems and methods for high efficiency power conversion

A high efficiency electric power arbitrating switch, the switch comprising:

• a first port configured to couple to an electric power converter, wherein the first port received a first electric power output from the electric power converter;
• a second port configured to couple to an electrical energy storage device, wherein the second port receives a second electric power output from the electrical energy storage device;
• a third port configured to provide a third electric power output from the switch;
• a first sensor that measure a charge level of the electric energy storage device;
• and
• a second sensor that measure a power demand drawn from the third port;
• wherein the power arbitrating switch switches the third electric power output between being supplied by the first electric power output and being supplied by the second electric power output based on the power demand and the charge level;
• wherein the power arbitrating switch further comprises a power setting corresponding to a target peak efficiency of the electric power converter;
• wherein when the power arbitrating switch determines that the electrical energy storage device is not sufficiently charged to meet the power draw:
• the power arbitrating switch feeds the third electric power output from the first electric power output;
• and
• the power arbitrating switch further loads the electric power converter to the target peak efficiency by charging the electrical energy storage device using at least part of the first electric power output.

A method for operating a high efficiency electric power converter circuit using a power arbitrating switch, the method comprising:

• determining when an electric power converter is supplying electric power to a load at a target peak efficiency;
• determining when an electric power storage device has a sufficient charge to meet a power demand from the load;
• when the electric power converter is supplying electric power to the load at less than the target peak efficiency, operating the power arbitrating switch to charge the electric storage device with power from the electric power converter;
• and
• when the electric power storage device has a sufficient charge to meet the power demand from the load, operating the power arbitrating switch to switch from the electric power converter to supply electric power to the load with power from the electric power storage device.
