| Abstract |
A new layout design for the construction of pulsewidth modulated power converters with intermediate DC link is presented in the paper. It is based on a special way of interlacing the different power components of the inverter (rectifier diodes, inverter switches and free-wheeling diodes) and on the parralleling of a number of low power devices. Voltage spikes during fast commutations are reduced to a great extend hence eliminating lhe need of clamping. The proposed converter structure performs important parasitic inductances reduction and minimization of parasitic capacitances. The quality of commutation is improved, turn-on and turn-off processes are better controlled. The use of several low ratings power components assembled in standard low cost packages brings down the cost of the converter. High quality/cost ratio is achieved with the design we propose. |
