Description

The power circuit of a frequency inverter consists basically of a mains rectifier, theDC-link and an inverter at the output. The mains rectifier consists of an uncontrolledsingle or three-phase bridge connection, the single-phase design is restricted tosmall powers. It converts the AC-voltage of the mains into a DC-voltage, which issmoothed by the DC-link capacitor, thus in the ideal case (inverter unloaded) theDC-link is charged with a voltage of UZK = Ö2 . UN.Since during the charging of the DC-link capacitor very high currents flow for a shorttime which would lead to the tripping of the input fuses or even to the destruction ofthe mains rectifier, the charging current must be limited to a permissible level. This isachieved by using an inrush current limiting resistor in series to the capacitor. Afterthe charging of the capacitor is completed the limiting resistor is bridged, for example,by a relay and is therefore only active at the switch-on of the inverter.As the smoothing of the DC-link voltage requires a large capacity, the capacitor stillhas a high voltage for some time after the disconnection of the inverter from themains.The actual task of the frequency inverter, to produce an output voltage variable infrequency and amplitude for the control of the three-phase AC motor, is taken overby the converter at the output. It makes available a 3-phase output voltage accordingto the principle of the pulse-width modulation, which generates a sinusoidal currentat the three-phase asynchronous motor
