For the problem that traditional output voltage of sine wave inverter has linear or nonlinear distortion, a design method class D power amplifier circuit based on sine wave inverter has been proposed. The shortcomings of traditional inverter such as class A, AB class power amplifier circuit have beenanalyzed. In terms of the shortcomings, circuit based on IR's class D chip IRS2092S core has been designed and verification experiments have beencarried out. The results show that the method not only can effectively solve the problem of intermittent inductance loads distortion in the traditional sine wave inverter, but also have efficiency and applicability.
