High-density gas discharge lamp starting and operating circuit - gives optimum matching of lamp operating voltage during both initial heating and subsequent operating phases

The circuit has a DC/AC converter coupled to the DC inputs employing a transistor switch, a transformer with respective capacitors across its primary and secondary windings and a pulse width modulator with a HF generator providing an operating signal for the transistor switch. A blocking delay eleme...
