A new class of Switched-Linear Converters

This article presents a new class of hybrid converters named Switched-Linear (SL) Converters that can operate as a DC-DC, DC-AC or AC-DC converter. The idea is originated from conventional linear power amplifier integrated with a switched power converter. The linear power unit/cell is a power amplifier, which is fed by two tracking power supplies to boost the efficiency of the linear unit without scarifying any virtues of linear power amplifier. It can be achieved making the voltage in the linear amplifier the lowest possible level and adequate to application. The main goal is to guarantee the possibility of drain reversal power energy whenever it processes reversal power flux and/or non-resistive loads. Therefore, by combining the linear power amplifier with the switched power amplifier, the system has synthetic performance of high fidelity, high efficiency and excellent dynamic characteristics.
