In order to address the matters of traditional inverter, including complex design of control circuit, high cost, poor quality of the inverter output waveform, and high current distortion rate, this paper adapts the DCDCAC inverter topology. In the preceding stage of DCDC module, the ASIC SG3525 is used and the peripheral circuit is designed to obtain PWM that has 0.4 duty cycle. It can turn 48 v DC input into 400 v output of high voltage pulsed DC. In the backward stage of DCAC module, it employs the ASIC TDS2285 to produce highprecision SPWM wave without noise. In addition, it achieves the fullbridge inverter control output by control dead time precisely. The fullbridge inverter control output can generate sine wave that is made of the frequency of 50 Hz and the amplitude of 220 V. The output voltage changes within 2% and the frequency changes between -1 Hz and +1 Hz in the state of full load, electric energy efficiency can be achieved 80%. Meanwhile, this paper also studies the calculation and choice of parameters of boost, drive circuit in the process of inverter, transformer and filter. The result shows that the DCDCAC inverter topology using the special control chips is simpler and the inverter possesses better steadystate behavior and dynamic performance. In addition, the adaptability of the nonlinear load and the quality of inverter output are improved.
