This paper studied the sensitivity characteries of the electronic ballast for the discharge lamps, which implies variation ratio of the output power by the passive element variation. We have derived the equation to represent the lamp power, and obtained the sensitivity characteristic equations. The simulation result shows that the proposed equations are correct and very useful to design the electronic ballast with the LCpCs-type resonant tank.
