diode light bulb dimmers on 3 phase Y supply

Ran a simulation of a 3 phase 120VAC Y system, here the 144 ohm resistors are 100W light bulbs, and diodes all pointing in the same direction. The 1 ohm resistor on the neutral gave me a point I could measure neutral current. Neutral is seeing a lot of current. Three negative peaking bumps per 60 cycle.
