A three$-$phase dc$-$ac power converter is operated as grid forming converter, and maintains a fundamental three$-$phase balanced voltage of $415$ V$,60$ Hz at its terminal using SPWM switching method. A balanced load of $20-$j$50$ Ohm in each phase is connected to the converter terminals. Consider the load is delta connected. What will be dc source voltage connected at dc side if modulation index is $0\mathrm{.}85?$ What will be dq$0$ components of currents drawn by the load. The angle of $0$ is assumed for dq$0$ conversion.
