  • Page 3: General Description

    General Description Inverter The figure beside shows the connection of a switchmode inverter and a transformer. The figure below shows the circuit of the inverter: The intermediate circuit voltage (DC-input voltage) is transformed by the power transistors T1-T4 with the parallel inverse diodes D1-D4 in a pulse-width square-wave voltage. The choke with the windings LI and LII integrates this voltage, and at the capacitor C there is a sinusoidal output voltage.
