Figure 1. Electronic analog control of the armature speed
A way out of this situation can be found in the use of pulse-width modulation
(PWM), however, such attempts were made [148], but they did not receive
sufficiently wide development due to the absence at that time of powerful and reliable
power switches based on MOS (metal-oxide -semiconductor) transistors.
Conclusion
Thus, the electrical equipment of modern cars has become a constantly evolving
complex system that requires qualified maintenance. Correct and cost-effective use of
vehicles depends largely on the availability of electrical equipment. The cost of
electrical equipment in modern cars is much higher, accounting for 25-30% of the
total cost of a car. The cost of repair and maintenance of electrical equipment is about
the same. Therefore, it is important to thoroughly and comprehensively study the
features of improving the system of electrical equipment of cars based on adaptive
power converters.
