ABSTRACT:
An inverter circuit having two pairs of transistors, the transistors of each pair thereof being connected in series to alternately and repetitively apply electrical energy to an inductive load such as a fluorescent lamp. A square wave voltage is applied in opposite phase to electrodes of a first transistor of each pair thereof for rendering them alternately in condition for conduction and nonconduction. Each time a first transistor of one pair thereof becomes nonconductive, current in the inductive load reduces and an inductively induced flyback voltage is generated therein, which voltage is applied to the base electrode of the second transistor of the other pair thereof for creating a stored charge which turns on this transistor and keeps it on during the half-cycle, whereby the pairs of transistors are alternately turned on and off for applying alternating current through the load. Rapid discharge circuits are provided for the removal of residual stored charges.
