An attractive new converter topology for AC/DC, DC/DC & DC/AC power conversion
A new power converter topology is proposed. The new converter is essentially a four-quadrant converter offering several advantages. These include high efficiency, reduced size and weight, excellent dynamic performance, and inherent galvanic isolation. The new topology proposed has the potential for a wide range of applications such as: inverters, rectifiers, and step-up step-down four quadrant converters for special applications. The key features as a rectifier are sinusoidal current absorption and unity power factor in both single-phase and three-phase operation. Special emphasis is given to the design of a 50 VA single-phase inverter for telecom applications (19 to 26 Hz ringing generator). The simplicity of the scheme proposed allows galvanic isolation between DC source and AC load without the requirement for a low-frequency transformer or DC/DC preregulating stage. In addition, a new diagram for a single-phase and three-phase rectifier based on the same principle is described in detail.<>
