Abstract It is well-known that in mines for mining equipment supply is used the high voltage values (U = 1140/660 V). Besides, the safety system’s devices are based on chip components that used the spark-safe voltage of lesser of 5 V. Taking into account this fact, for automation systems supply a lot of companies produced the low-voltage power supplies. To convert the high-voltage into low-voltage are used transformers or high-voltage capacitors in pulsed power supplies. These devices have a significantly overall dimension and are needed to use a bulk explosion-safe protective covers. There is also difficult problem of the electro-magnetic pulses safety. These pulses are occurred while switching the electrical motors with power.
