The 5th harmonic is always the greatest contributor to a THD in all three phase bridge rectifiers. A high frequency ripple voltage, induced by inverter current, causes two negative effects ...

Conventional 3-phase rectifiers employ six diodes, but the diodes drop voltage and dissipate significant power at just a few amperes of load current. This requires costly heat sinking and active ...

Linear Technology has created at three-phase ideal rectifier reference design ... Power dissipation drops from roughly 1.2x the output current to 0.04x the output current if the correct mosfets are ...
