The invention proposes a multi-phase pulse converter operating in limit-interrupting mode. The multi-phase pulse converter includes input terminals connected to first inputs of N power channels with throttle current zero sensors, to second input of which through N drivers it is delivered control signals from N typical controllers. First of power channel outputs with throttle current zero sensors are united and connected to output terminals and to first inputs of typical controllers, to second inputs of which it is delivered synchronization signals from decade counter/divider outputs, input of which being connected to output of a voltage-to-frequency converter. Input of the voltage-to-frequency converter is connected to low-pass filter output with a trigger and majority system being connected to it. To fist N inputs of the trigger and majority system signals from the counter/divider are delivered, second N inputs are connected to second outputs of power channel with throttle current zero sensors. Output of the trigger and majority system is connected to input the low-pass filter. Also between typical controllers and drivers it is entered N control signal block systems, second inputs of which being connected to second outputs of power channels with throttle current zero sensors. To third inputs of control signal block systems it is deliver synchronization signals from the decade counter/divider. |
