(2) rx is used to limit the voltage when both lamps are removed. an equalizer transformer t eq is used to equalize the lamp currents needed in deep dim settings. the uba2015at controller starts at 100 khz and sweeps down until the preheat frequency is reached. the resistor on pi n ph/en sets the preheat frequency. during preheat, the lc tank voltage remains belo w 200 v to prevent early ignition and glow. fig 9. half-bridge topology c res 4.7 nf lamp y lamp x c fil tyc 4 h txc 4 h tyb 4 h txb 4 h c fil tya 127 h txa 127 h teqa 2 x 33 mh 21 l res 2 mh 2 5 teqb 34 c dc 220 nf q highside q lowside r x 10 k c x 56 nf 420 v (dc) 150 nf 150 nf c fil c fil 150 nf 150 nf lamp lamp aaa-001521 f res 1 2 ? l res c res ? ----------------------------------- f res 51.9 khz = ? = f sec 1 2 ? l txa l tya ? l txa l tya + ---------------------------- - c x ? --------------------------------------------------- f sec 84.8 khz = ? =
