Matlab/Simulink Modeling of Parallel Resonant DC Link Soft-Switching Four-leg SVPWM Inverter
This paper suggests the use of the traditional parallel resonant dc link (PRDCL) circuit to give soft switching to the Four-leg Space Vector Pulse Width Modulation (SVPWM) inverter. The proposed circuit provides a short period of zero voltage across the inverter during the zero-vectors occurrence....

| 總結: | This paper suggests the use of the traditional parallel resonant dc link (PRDCL) circuit to give soft
switching to the Four-leg Space Vector Pulse Width Modulation (SVPWM) inverter. The proposed circuit provides a
short period of zero voltage across the inverter during the zero-vectors occurrence. The transition between the zero
and active vectors accomplished with zero- voltage condition (ZVC), this reduces the switching losses. Moreover, the
inverter output voltage Total Harmonic Distortion (THD) not affected by circuit operation, since the zero voltage
periods occur simultaneously with zero-vector periods. To confirm the results, balanced and unbalanced loads are
used. Matlab/Simulink model implemented for simulation. |
