The Phase-Neutral RMS voltage would be V_an_rms = 1/sqrt(2) *ma*Vdc/2. Reason: The maximum peak voltage is always measured to a "virtual" neutral point of the DC link capacitor split in half. E.g. the maximum peak voltage (with mi = 1.0 - no overmodulation) is V_an_pk = Vdc / 2. From this value you can calculate RMS Line-Neutral voltage easily.
