Document Type and Number:
Japanese Patent JPS58501255
Kind Code:
A
Abstract:
Converter, particularly for supplying a discharge lamp (E) with a rectifier (G), a unit with a self (L), a charge diode (D) and a charge switch (T2, T2') as well as a charge capacitor (C) and an inverter provided at least with two alternately controlled switches (T1, T3), referred to as primary and secondary switches, which are connected in series and in parallel to the capacitor (C). The object of the invention is a simple control of the charge switch (T2, T2') with an automatic locking of the charge switch when turning the inverter off. To this effect, the control of the charge switch is synchronized by a square voltage to one of the switches (T1, T3) of the inverter.
