Abstract

Improvements in circuits to reduce the voltage stress of a circuit governed by a vibrator, whose circuit comprises a main thyristor that is in series with the load, an extinction circuit parallel to the main thyristor composed of the series connection of an extinguishing thyristor and of an extinguishing capacitor with bridging of the extinction thyristor by a load change reactance coil connected in parallel with it and a recharging circuit also, parallel to the main thyristor and composed of the series connection of a reactance coil of recharging and an anti-parallel recharge diode to the main thyristor, characterized in that in said circuits load is connected to the junction point between the recharge reactor and the recharge diode so that the charge current flows through the main thyristor and reload ballast.
