Abstract

The Z-source network, as a DC-link energy storage sub-circuit, was proposed to be used in DC-AC power conversion circuits (inverters) due to its advantages compared to the traditional LC DC-link. In this paper a new modified Z-source (MZS) network is proposed in order to reduce the number of switches in a single-phase inverter, from four switches, in a full-bridge converter, to only two switches, as well as to maintain the desired average voltage level in the DC-link. This paper presents the novel topology and the operating principle of the new MZS single-phase inverter with two switches, and an application of this converter in a motor drive system to a single-phase PM synchronous motor. The proposed system topologies are validated by digital simulations of the circuits in PSIM and SIMULINK, with tests due soon.
