Abstract
A master-slave control architecture for inverters includes a master control circuit board which has a master control unit to output a plurality of frequency signals of the same phase and same frequency so that driving units on a plurality of separated slave control circuit boards on the rear end can be driven synchronously by the frequency signals to control electricity input of transformation units to transform voltage for outputting. Thereby the frequency of the driving electricity of the discharge lamps can be synchronized to maintain uniform luminance.
Claims14
A master-slave control architecture for inverters, comprising:
- a master control circuit board which has a master control unit to output at least two frequency signals of a same phase and a same frequency;
- at least one slave control circuit board separated from the master control circuit board, each slave control circuit board having a driving unit and a transformation unit that are connected electrically, the driving unit being synchronously driven by at least one of the frequency signals output from the master control unit to control electricity input of the transformation unit to transform voltage for outputting;
- and
- at least one discharge lamp which is electrically connected to the transformation unit and driven by the electricity output from the transformation unit.
