I understand from your query that the solar and wind energy systems need to be connected to the common DC bus or the load (the output resistor in this case). The different ways this can be done are as follows:
- The 3-phase output from the block Permanent Magnet Synchronous Machine can be connected to a 3-phase uncontrolled diode rectifier. The rectifier can be implemented using six Diode blocks (available at Simscape/Electrical/Specialized Power Systems/Power Electronics). To reduce harmonics, the output of the rectifier can be filtered using a capacitive filter to feed the DC load.
- The 3-phase output from the block Permanent Magnet Synchronous Machine can be connected to a 3-phase controlled rectifier. The difference from the previous technique is six controlled switch blocks like Mosfet (available at Simscape/Electrical/Specialized Power Systems/Power Electronics) have to be used here. An appropriate control algorithm can be developed to provide PWM pulses to the gate of the Mosfet. In this case too, a capacitive filter can be added in cascade to feed the load.
Hope this helps resolve the query.
