Selection of power blocks:
Depending on the load of power block there are used different semiconductors.
Size of the applied semiconductor is specified in Table 1.
Working conditions:
Double-element power blocks are assigned to work in power electronic inverter systems:
• temperature of cooling water on entry: 50C – 300C for temperature of ambient air not lower than -100C;
• atmospheric pressure: 860hPa – 1060hPa;
• cooling water: resistivity not lower than 5x105 Ω•cm, pH: 5 – 8 and hardness
not higher than 80mg CaO/dm3
