ELECTROMAGNETIC COMPATIBILITY POWER SOURCE WITH RELAY CONTROL

Abstract

In the development of modern devices of converter technology, one of the most important tasks is to ensure electromagnetic compatibility with the network. Power sources are classified on voltage source, current sources and power sources. The quality of their work is determined by accurate implementation of these conditions. The main aim of the research work is the creation of power source with relay control and analysis of its operation modes. The power source is built on the principle of forced sinewave current rise, which is consumed from the circuit and from the relay control. The suggested principle solves the problem of electromagnetic compatibility and terminal processing speed. Power source has two circuits, two looped circuits. The first one secures looping courses of sine-shaped current, which is consumed from the circuit. The second one is used for power stabilization on load. The following research presents the analytical data for relay mode frequency identification while mains current and power on load formation, The expression for capacitance is the capacitor. Thus, the system of invariant stabilization towards the disturbance influence of THD is much lower acceptable value specified by the State Standard. Under this conditions the voltage consumed preserves the sinewave form, where cosφ=1.
