The LCL filter is effective only if proper damping is added. Passive damping, realized with a
resistor series connected to the filter capacitor was used for this application. The value of
the resistor is chosen to be one third of the impedance of the capacitor at the resonant
frequency:

Selection of semiconductor devices
The semiconductors selected for the DC-AC section are 600 V, 35 A IGBTs with internal fast
diodes used to minimize the effect of recovery at turn-on. The choice of IGBTs is a trade off
between cost and efficiency. The part number of the device used is STGW35HF60WD,
which shows very good performance in terms of switching losses. The electrical
characteristics of this device are shown in Table 5.
The power losses in each IGBT may be calculated considering conduction losses, switching
losses and diode losses.
Conduction and switching losses in IGBTs may be evaluated according to the following
equations:
