PARAMETERS OF THE COMPONENTS OF THE HIGH VOLTAGE NETWORK OF ELECTRIC CARS AND THEIR CALCULATION

Abstract

The article considers the components of high-voltage networks of electric cars and their relationship with the components of low-voltage networks, as well as the methods of their conversion. The dependence of the weight and size parameters on the voltage of the electric car high-voltage network is shown. The calculations showed the possibility of using the "voltage drop" parameter in the wires to control the current strength without using additional shunts. The distinctive features of the output power switches and the inverter driver circuit are shown. The operation of a single-phase bridge circuit with four different switching states is analyzed. The principle of organizing a sinusoidal form using pulse-width modulation is shown, with a given oscillogram of the generated signal. The synthesis of a threephase alternating current system is shown. The parameters of the absolute and relative slip of the motor rotor are determined by reading the rotational speed and position of the motor rotor and the rotating magnetic field of the stator when reading from the output stages of the inverter.
