A transistor invertor circuit is described, in the case of which a first DC input lead (1a) is connected to the centre tap of a primary winding (11a) of a transformer (11), and a second DC input lead (1b) is connected to the interconnected emitters of two transistors (4, 5). The collector of the one transistor (4) is connected to the one end of the primary winding (11a), and the collector of the other transistor (5) is connected to the other end of the primary winding (11a). Connected in one (1a) of the DC input leads is an inductor (2) which, together with a commutating capacitor (12) which is connected to the ends of the primary winding (11a), forms a tuned circuit. A secondary winding of the transformer is connected to two AC output leads (15a, 15b). The transformer furthermore has a control winding (6) which has a first connection, which is connected to the base of the one transistor (4), as well as a second connection, which is connected to the base of the other transistor (5). A series circuit comprising a capacitor (9) and a resistor (10) is connected between the emitters of the transistors (4, 5) and the first connection of the control winding (6), and a diode (8) is [lacuna] in order to form a charging circuit, which charges the capacitor (9) to a controlled DC voltage whose polarity is in the forward direction for the transistors (4, 5), on the one hand to the junction point between the capacitor (9) and ...
