A DC/AC converter (30 to 72) for feeding a low-pressure mercury vapor discharge tube (15) comprises two series-connected main transistors (11 and 20) which, in the operating condition, are alternately conducting. The conduction times of the two transistors (11 and 20) are always kept equal to each other...http://www.google.fr/patents/US4684851?utm_source=gb-gplus-shareBrevet US4684851 - DC/AC converter for feeding a metal vapor discharge tube
