The protection of the IGBT's in the case of an over-current or a short-circuit, respects the general methodology of a power electronic device protection. Usually, every power device is protected by its driver, which becomes a multifunctional circuit capable of assuring the driving signal, monitoring the operation state as well as providing its protection. In this paper we propose and realize a protection...
The paper presents the design key issues for a plasma generation method. A Class E Power Amplifier is used to generate plasma at 13.56MHz with a variable load implemented with an air coil and a variable capacitor. Class E amplifier represents a mean of high efficiency power amplification. Ideal amplifiers reach 100% efficiency and by proper filtering and tuning even the real circuit efficiency can...
