conversion equipment, induction heating of metals. SUBSTANCE: inverter incorporates first, second, third and fourth transistors, input first and second capacitors, first and second load capacitors, load inductor. First and second input capacitors are connected in series and are connected to power supply of inverter. Besides it, first and second capacitors are connected correspondingly to first and second transistors and third and fourth transistors connected in pairs. First load capacitor, load inductor and second load capacitor are connected in series and form series oscillatory LC circuit. Load of inverter is connected to connection points of first, second, third and fourth transistors. Transistors work under key condition in turn. Voltage of corresponding capacitor, that is, half-voltage of supply of inverter is applied to cutoff transistor. EFFECT: expanded boundaries of range of working frequencies of inverter, increased stability of parameters of output signal of inverter, raised functional reliability of inverter. 2 dwg
