Abstract
Many electronic ballasts for low pressure discharge lamps as fluorescent lamps are produced and commercialized. However, the electronic ballasts for high pressure lamps are now in progress to because of poor reliability and high cost of production. To obtain the confidence of electronic ballasts, it is necessary to prolong the life time of output switches. A variable frequency driver for inverter switches that can control the magnitude of output current with temperature of switches was designed and simulated. A conditions for circuit design are 22kHz : standard frequency,
