A procedure and an apparatus for converting a first alternating voltage into a second alternating voltage with respect to frequency and amplitude by means of first (1) and second (2) bridges having switches (T1 . . . T12), and a resonant circuit (3) connected between the bridges. The invention also relates to the use of a frequency converter for the control of a motor. The voltages of a supplying network and the voltages of a load (M) are connected across the resonant circuit (3) in an alternating fashion by means of bridge switches (T1 . . . T6) and bri...
