Voltage link control of a DC-AC boost converter system

This invention describes a power system that takes direct current (DC) and converts it into alternating current (AC) for a load. It uses a boost converter to increase the voltage of the DC input before feeding it to a specific type of inverter called a single-source multi-phase inverter. The boost converter itself uses an inductor and two switches, which are controlled to manage the power flow.

Why it matters: Power semiconductor and microcontroller technology has advanced significantly since 2007, making efficient and compact control of such converters more feasible and cost-effective. This could enable smaller, more efficient designs for the boost converter and its control system.
