FIELD: electricity.
SUBSTANCE: there is proposed a variable signal converter including N variable signal amplification cascades, connected in parallel, where N is a natural number, containing two or more direct voltage sources each acting as the power supply unit for its individual variable signal amplification cascade, the difference consisting in the variable signal converter having a direct (immediate) connection of load to the output and including N connected cascades of variable signal amplification and conversion form a rectangular shaped signal into any shape specified; power supply of the variable signal amplification and conversion cascades of the converter concerned is provided from a power supply source which is common for any or all variable signal amplification and conversion cascades of the converter concerned or from two or more direct voltage sources each acting as the power supply unit for its individual variable signal amplification and conversion cascade with the voltage of the power supply of its individual variable signal amplification and conversion cascade being as assigned (calculated) by the assigned signal shape; additionally, the variable signal converter concerned may include units for protection and coordination of the variable signal converter that automatically uniformly distribute the total load on the amplification and conversion cascades in such a way that the current delivered to one or several amplification and conversion cascades is redistributed onto other amplification and conversion cascades. The output coordinating element (transformer) on primary windings connected to amplification and conversion cascades has a number of coils calculated from the assigned output signal formula; on amplification and conversion cascades a variable signal shaped as the assigned output signal has its length modulated; then at the output coordinating element (transformer) variable signals produced on amplification and conversion cascades are aggregated into a signal of arbitrary shape. Two or more variable signal amplification cascades have a transformer or any other output excluding direct contact of amplification and conversion cascades with each other. One has added circuits of protection and coordination of the variable signal converter that automatically redistribute the total load in excess of the allowable value on amplification and conversion cascades. The output coordinating elements (transformers) perform a amplification (transformation) between the primary and the secondary winding(s) calculated by the assigned signal shape; on each amplification a variable signal of a rectangular shape Is modulated in terms of duration with the duration modulation proceeding by the assigned output signal shape. One has added to the variable signal converter circuits for output voltage stabilisation by way of modulating amplitude and duration at unified inputs of amplification and conversion cascades. Diodes included in amplification and conversion cascades and interconnected via anodes and cathodes by a connection provide for power supply of the controlling generator-multivibrator unit with each diode connected to its individual direct voltage power supply source.
EFFECT: high efficiency, low losses of heat and power, low prime cost.
