| 摘要 |
The invention relates to a constant-voltage range expansion circuit in which a rectified high voltage is applied to a constant-voltage part at a low input voltage and a rectified low voltage is applied to this constant-voltage part at a high input voltage, especially such a circuit for the expansion or extension of the input voltage range and for the reduction of a loss (damping) in the rectifier output circuit in the case of a low input voltage. <IMAGE>
