PURPOSE: A DC generator is provided to prevent life expectancy of a smoothing condenser from being reduced and output loss from being occurred by inserting a metallic thin film condenser to the smoothing condenser in parallel. CONSTITUTION: A resistance(306) is used to drive SCR. Condensers(316,318) are smoothing condensers to convert an AC power to a DC. The condensers(316,318) are electrolytic condensers for low frequency of 120Hz and have a rated capacity of 15,000uF/160V. Meta thin film condensers(320,322) for high frequency are inserted to the two smoothing condensers(316,318) in parallel. While the smoothing condensers(316,318) for low frequency have the rated capacity of 1500uF/160V, the metal thin film condensers(320,322) for high frequency have a capacity of 0.47 to 1uF. A high frequency signal inputted to a circuit is bypassed through the metal thin film condensers(320,322), such that the smoothing condensers for low frequency are not affected by the high frequency.
