Method for processing PWM waves intended for a voltage inverter or a voltage-controlled rectifier, comprising at least one set wave with at least one pair of switches, this inverter or rectifier being controlled by a one signal having the sequence of high level and low level created by the modulator, the high level is defined by the fact that the switch connected to the most positive load is closed while the switch connected to the most negative load is open, and the low level is defined by the reverse characterized in that two set signals, corrected as a function of the direction of the current in the load or in the source, are applied to the discriminator, the corrected set wave for the output current has a high level to which a delay is added during transition from the high level to the low level, and the corrected set wave for the input current has a low level to which a delay is added during transition from the low level to the high level. |
