波形に加算することを特徴とする同期整流装置。In a synchronous rectification device that rectifies the output voltage of a synchro control transformer, etc. based on the instantaneous polarity of a reference input voltage, the input voltage of the synchro control transformer, etc. is rectified by the synchronous rectifier circuit.
Synchronous rectification is performed using the reference input voltage, and the polarity of the rectified waveform is detected at a point with a constant phase shift from the zero-crossing point of the reference internal input voltage, and depending on the polarity, only the positive polarity portion of the synchronous rectification waveform or Similarly, a synchronous rectification device is characterized in that only a negative polarity portion is selected, inverted, amplified twice, and then added to the synchronous rectification waveform.
