SINGLE PHASE HIGH EFFICIENCY POWER SOURCE FOR DC ELECTRIC DRIVES

This paper presents the circuit realization single-phase stabilization system current, active power filter and control system is simplified in comparison with the known. Active power filter is made by a single-phase bridge circuit, the two lines of which are made in two IGBT - transistor, the other two lines - two capacitors. Presents analytical research of processes in the active power filter, to derive equations showing the relationship of magnitude ripple voltage on the capacitor to the network frequency, capacitance, voltage of the network and power of load. Expressions are obtained for calculating the value of the capacity of condensers the filter and frequency of relays mode. Shows the dependence of the frequency of the load current for different values of resistance and inductance. Invariance of the system to stabilize is shown to the action of disturbances. Shows oscillograms of the electric drive based on the proposed stabilization system for two versions: with speed control and position control. In both cases, the drive is electromagnetically compatible with the network.
