NOVELTY - The method involves transmitting the electrical energy stored in the intermediate circuit capacitor (44) of sub-module to the outputs (30,32) of the inverter (42). The transmitted alternating voltage (58) is output to the electrical load (10) connected to the inverter of sub-module, until the voltage (72) at the intermediate circuit capacitor is reduced to a predetermined threshold voltage. The malfunction in the power converter circuit is detected, and the direct current (DC) voltage emitting power source is turned off after the malfunction of converter circuit is detected.    USE - Method for discharging intermediate circuit capacitor of sub-module of power converter circuit (claimed) used for electrical power supply to motor windings of electric motor in vehicle.    ADVANTAGE - The ohmic load resistor can be used for converting the energy stored in the intermediate capacitor into heat so that separate circuit for discharging the intermediate circuit capacitor is redundant. The discharge of the DC link capacitor of the connected electrical load of the sub-module is performed in order to avoid redundancy. The predetermined threshold value can be any value that is sufficient to convert the DC link capacitor of the specific sub-module in a safety-critical state. By avoiding redundancy in various sub-modules of converter circuit, the costs and installation space for the technical implementation of the sub-modules in the converter circuit can be saved throughout the converter circuit. The damage caused by people or other technical elements in the event of an intentional or unintentional opening of the housing and an accidental contact with the sub-module circuit can be avoided. The sub-module is taken out of power circuit of the inverter circuit, without being affected by other sub-modules of the interruption of power supply to the given sub-module. The high current spikes that cause damage to the electrical load can be avoided. The system with two-point control with built-in hysteresis, prevents the oscillation of output current flowing through the electrical load. The damage caused by people or other technical elements in the event of an intentional or unintentional opening of the housing and an accidental contact with the sub-module circuit can be avoided.
