<p><P>PROBLEM TO BE SOLVED: To suppress variation in amplitude of an AC voltage to be applied to a load device easily. <P>SOLUTION: The voltage variation suppressor is interposed between an AC power supply and a load device and suppresses variation in amplitude of an AC voltage outputted from the AC power supply prior to voltage application to the load device. The device comprises a voltage regulating section having a voltage limiter circuit composed of a plurality of Zener diodes connected in series with their forward directions opposite to each other and outputting an AC voltage obtained by applying the AC voltage to the voltage limiter circuit, a voltage input section for applying the AC voltage outputted from the AC power supply to the voltage regulating section, and a voltage output section for applying the AC voltage outputted from the voltage regulating section to the load device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
