چکیده انگلیسی
In this paper, a new topology for Z-source half-bridge inverter is proposed. This topology is achieved by using LC networks in conventional half-bridge converter. The proposed inverter can produce symmetric and asymmetric voltages with different amplitudes during positive and negative half-cycles. By appropriate value of duty cycle it is possible to achieve the conventional half-bridge characteristics. Other advantage of this inverter is producing zero voltage level at output. It is noticeable that the conventional half-bridge inverter cannot generate zero voltage at the output. This inverter can be used in different applications in industry such as electrochemical, electroplating and residential applications. In this paper, the steady state analysis of the proposed inverter in different operating modes is presented. Moreover, the calculations of voltage stress of capacitors, current ripple of inductors, voltage ripple of capacitors, and power loss of the proposed inverter are presented. Then, design of proper values of inductors and capacitors is given. To show the advantages and disadvantages of the proposed topology, it is compared with some conventional topologies. The correct operation of the proposed topology is reconfirmed by simulation and experimental results.
