Research On Inverter Based On Single-Stage Boost DC/DC Convertor

In this paper, There topologies of inverters based on Single-Stage boost DC/DC converter are researched. And two of them are first proposed. These topologies of inverters are composed of two Bi-Boost DC/DC converters, they are symmetry. So whole circuit turn into four-quadrant converters, we can control every power MOSFET on or off. Then we can get sine wave with direct current polarization at the left, at the same we also can get sine wave with direct current polarization phase contrast 180°compared of the left at the right. At last on the load, a sine wave is generation.The three operational modes, steady principle, control strategy , and design criterion of key circuit parameters are investigated. The simulation results are given. The prototype for inverters based on Single-Stage boost DC/DC converter are designed and developed. The test results are given and corresponding to the theoretical analysis. The test results demonstrate that the inverter has the advantages of single stage power transfer, uninterruptible power supply, small size, lower weight, low cost. The inverter can be used application field in the telecom, computer industry and so on.
