Design methodology - Single-Phase vs Three-Phase Inverter
The current ripple will be higher by about 50% in the single-phase inverter if you go with the same switching frequency (which means the same semiconductor losses). So you might increase the inductance and/or increase the switching frequency. 

In single-phase the power is not constant any more, but pulsates with two times the fundamental frequency. Therefore, you will see a low-frequency voltage ripple on the DC link, and you might need to increase the DC link capacitor (significantly). 

To take into account the voltage ripple on the DC link in the single-phase system, you will probably have to change the voltage-control loop dynamics and make the voltage controller slower to avoid instability.
