Abstract
A DC to AC converter includes an input configured to receive a DC input voltage, an output and two serially connected capacitors connected across the output. The two serially connected capacitors including a first capacitor and a second capacitor connected together at a connection node. The converter also includes a first parallel converter connected between the input and the connection node and a second parallel converter connected between the input and the connection and in parallel with the first parallel converter. The converter also includes a controller that selectively connects the first and second parallel converters to the input based on a first duty cycle (D) and second duty cycle (D), respectively. The controller determines Dbased on comparing a desired alternating current signal across the second first to a measured alternating current signal across the first capacitor such that Dvaries over time.
