STEVAL-3KW3PFCCB

概要

The STEVAL-3KW3PFCCB board is the practical implementation of a 3.3 kW PFC boost module which is the major front end building block for any mains fed power conversion system.

It may be an EV charger, telecom power supplies, air-conditioners, or general high-power SMPS applications.

It has a compact form-factor: 125 x 180 x 60 mm3 and is intended to deliver full power under forced convection cooling at the EU voltage range.

It may be run in the universal range as well but, the output power must be derated accordingly to limit the current drawn from the mains and temperature rise of the heatsink.

The electrical specifications have been derived keeping in mind standard applications.

This board allows the engineer to evaluate a wide range of power output options.

Anything from sub 1000 till about 3300 W may be evaluated using this board by replacing the power MOSFETs with suitable types and optimizing the gate drive resistors.

STW57N65M5 and STW69N65M5 have both been tested to be very suitable for targeting the 3000 to 3300 W power levels with no other changes required in this board and consistent performance figures.
