| Abstract |
PWM inverters are very suitable for eliminating lower frequency harmonics which generate vibrations and losses. The use of power MOSFET transistors allows good accuracy for the switching angles and the use of a microprocessor increases control flexibility of the inverter drive. The advantages and drawbacks of power MOSFET transistors have been reviewed. Then a circuit which protects these transistors against overvoltage transients has been devised. This allows to use them up to 2/3 of the transistors drain-source breakdown voltage with their normal current. |
