DIGITAL AC/DC POWER CONVERTER |
| 摘要 |
A digital AC/DC power converter comprises an active PFC module, a single switch module having a single switch, a power output module having a transformer, and a digital control module having a microcontroller. The single switch is electrically connected to the active PFC module, and a primary winding of the transformer is electrically connected to the active PFC module. Moreover, the microcontroller provides a PWM signal to control the switching state of the single switch, so that the active PFC module transforms AC frequency from no more than 300 Hz into at least 30,000 Hz and outputs a rectified AC output voltage waveform to improve power factor. |
