| Title: |
Sine Wave Light-Adjusting Apparatus |
| Abstract: |
A sine wave light-adjusting apparatus adjusts the input sine wave voltage
and output a desired output sine wave voltage to a lamp according to the
desired brightness of the lamp to achieve the light-adjusting effect by
adjusting the switching period of a switch and utilizing a flywheel
effect. The apparatus includes an energy-storing unit, a positive
semi-period switching unit controlled by the microprocessor to execute
the switching operation during the positive semi-period of the sine wave
voltage, a negative semi-period switching unit controlled by the
microprocessor to execute the switching operation during the negative
semi-period of the sine wave voltage, a positive semi-period flywheel
unit controlled by the microprocessor to conduct during the positive
semi-period of the sine wave voltage, and a negative semi-period flywheel
unit controlled by the microprocessor to conduct during the negative
semi-period of the sine wave voltage.
