Trong bản này. Một thiết kế cho mạch nguồn công suất cao trên 10Kw để chuyển đổi từ năng lượng nguồn DC sang nguồn năng lượng xoay chiều AC được sử dụng cho các ứng dụng trong thực tế.
The configuration is achieved using a high frequency dc-dc push-pull converter at the input side followed by a full-bridge PWM inverter and a low-pass filter at the output side. Due to the simplified power stage and the application of DSP-based sinusoidal pulse width modulation technique, output voltage Total Harmonic Distortion (THD) is reduced and a relatively smaller overall inverter size is achieved. The proposed practical circuit operates from a 48V DC fuel cell input and outputs a regulated 120V AC, 60Hz sinusoidal
voltage having 3-wire configuration[4]. A complete circuit analysis, design and cost evaluation is presented and supported by PSPICE simulation results. As per competition guidelines, a low power inverter has been redesigned, tested and prototyped, to deliver a 1.5kW load. Operating waveforms,
printed circuit board layout and measured efficiency of the actual circuit are also presented
