| Abstract |
Low frequency PWM control of a quasi-resonant voltage inverter associated with a suitable high frequency resonant interface is proposed. We can thus consider using this structure for high-power GTO applications, where the target frequency is several kHz, without including high value reactive elements. Actually, decoupling of resonante interface and the inverter is proposed concerning both QRDCLI structure and control. This approach requires modelling of the assembly formed by the oscillating circuit, the converter and the load. Theoretical analysis is validated by an experimental prototype based on digital control of the PWM quasi-resonant voltage inverter. |
