Half-bridge converter

Block appearance in REPEAT VISION

 The unit implements a model of a converter made according to the scheme of one bridge arm. The switching device of the converter is a special component, IGBT transistor, connected in parallel with the reverse diode. The bias voltage of the transistor and diode are not considered. RC damper circuit can be connected in parallel to each pair of these components.

 Switching devices of the converter are controlled by an input vector signal of the form [S1, S2] coming to the Control port. Indices of vector signal components correspond to numbering of switching devices in the diagram (see Fig. 1 below). Control can be carried out using Two level PWM generator when 1 arm is selected in Bridge converter type property, as well as using individual pulses generated by the Automation section blocks and collected into one vector signal with dimension equal to 2 using the Multiplexer unit.
