FIELD: electrical engineering.
SUBSTANCE: electrical unit contains a body (1) with power components grouped into power modules (4) and control components grouped into a control module (3) separated from the power modules (4) so that they are not in direct contact.
EFFECT: improvement of electrical unit reliability due to decrease of heating for control components up to the minimum value in result of convection or emission as consequence of power components heating.
