Degrees, calculate the average output voltage and the RMS output voltage.

To calculate the average output voltage, we need to find the area under the positive half-cycle of the rectified waveform. The average output voltage can be calculated using the following formula:

Vavg = (2 / π) * Vm

Where Vm is the maximum value of the input voltage, which is 400V in this case.

Vm = 400V

Vavg = (2 / π) * 400V
≈ 254.65V

Therefore, the average output voltage is approximately 254.65V.

To calculate the RMS output voltage, we can use the following formula:

Vrms = Vavg / √2

Vrms = 254.65V / √2
≈ 180.28V

Therefore, the RMS output voltage is approximately 180.28V.
