The development of highfrequency AC distribution systems poses new challenges to the requirements of inverters. Traditional inverters are no longer suitable due to their complex structure, high switching frequency, and lack of boost capability. Based on this, a novel singlephase capacitor self balancing five level inverter topology is proposed. This topology achieves five level output through a series parallel mechanism combining capacitors and power sources, and has the advantage of capacitor self balancing; Improve transmission efficiency by simplifying the structure and reducing switching frequency; Using specific harmonic elimination methods to further reduce output harmonic distortion. This article introduces the working principle of inverters and the calculation method of related parameters, and conducts simulation verification. The results indicate that the theoretical analysis is correct, indicating that the inverter is suitable as a power side device in the highfrequency field.
