Part Number: TIDM-BLPFC
Other Parts Discussed in Thread: TIDM-02013

hi ti team,

kindly suggest Soft switching PFC topology and any reference design for EV charger front end section

power range 500 W to 3.5KW

thank you

Hello Venkatesh,

Sorry, for the delay in responding to your question. Currently we have TIDM-02013 (https://www.ti.com/tool/TIDM-02013#design-products), the 7.4kW 1-ph AC OBC reference design. The AC-DC stage of this design is a TTPLPFC. But, the PFC stage is not a full soft switching solution as ZVS is achieved through synchronous rectification.

Thanks

Srikanth

Hi

one dount ,if zvs happens,then it is softswitching right?

Hi Venkatesh,

The soft switching is not happening for all the switches. ZVS is possible for synchronous rectification FET during turn on only.

Thanks

Sorry Venkatesh, we do not have a simulation available for this reference design.
