A charge pump DC/DC controller IC and four external MOSFETS eliminate magnetic components in a non-isolated intermediate bus converter (IBC). The combination provides 2:1 step-down ratio,1:2 step-up ratio, or 1: –1 ratio as an inverter.
As more U.S. engineers retire, the U.S. education system will be taxed to provide enough native-born replacement engineers. Or, this may require foreign-born engineers as replacements.
Pinpointing and developing new semiconductor materials, architectures, and fabrication processes is the charter of ARPA-E’s SWITCHES project.
