6CoolMOS? 600V P6 fits for Vienna PFC

Vienna Rectifier Characteristic*:

–Low blocking voltage stress on

MOSFETs could be used even for high dc-link voltage, i.e., for output

voltage 800V values with a blocking voltage capability Vds=600V can be applied–No current flow occurs through the body diode of MOSFET and/or a possible conduction of the body diode does not have to be suppressed by any other diode lying in series with the MOSFET

For three phase CCM Vienna topologyInput voltage is 230Vac pre phase and output voltage is 800Vdc (+/- 400Vdc)

–Significantly higher utilization of

MOSFET (conduction of each MOSFET during positive and negative half period of the related phase current), i.e., the lowest Rdson MOSFET should be used
