NOVELTY - The method for generating delay-control pulses for polyphase converters and direct voltage converters includes the steps of shifting a reference voltage (URef) (31) by a time delay or a dead time corresponding to that shift, and of shifting a pulse-width modulation (PWM) (32) signal by the dead time (T0) (33) which corresponds to the period (T) divided by the number (n) of shifts. A control voltage (USt) (30) is combined with the reference voltage (URef) corresponding to a triangular curve (31).    USE - In devices of converter type for transforming direct to alternating voltages or inversely alternating to direct, and also for converting one direct voltage to another of different voltage level, for use in electrical networks of automobile vehicles.    ADVANTAGE - The reference voltage variation is substantially of triangular form which is advantageous for the application of cent red PWM signal and improves electromagnetic characteristics.    DETAILED DESCRIPTION - The shifting of the reference signal (URef) is done by triggering a signal generator, or by a delay element which predetermines the time delay or the dead time (T0) (33). The shifting of a pulse-width modulation (PWM) signal is done by a digital delay element, or by a digital conversion by use of a shift register. The output PWM signal is a cent red PWM signal. The shifting of PWM signal is by use of digital counters in the case of the digital conversion of the delay control of half-bridges containing semiconductor elements; each time one of the digital counters corresponds to a positive edge and one of the digital counters corresponds to a negative edge of the PWM signal. In order to form a symmetric image of the reference voltage (URef) by shifting twice (n = 2), an inverter stage is used. In order to form a symmetric image of the control voltage (USt) by shifting twice, the voltage is applied to an inverter stage. The conversion of shifted voltage implemented in the form of an algorithm of program in a micro-controller or as a programmable logic.
