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...
A method for converting a first alternating voltage into a second alternating voltage with respect to frequency and amplitude using a first bridge having a plurality of branches and a plurality of first switches, each branch having at least one first switch, a second bridge having a plurality of second switches, and a resonant circuit connected between the bridges, the method comprising the step of: (a) connecting the first alternating voltage across the resonant circuit via at least two first switches of the first bridge for a first period substantially...
