2.2.1

Electronic connection

National accident prevention rules must be followed when working on the main power

supply, with the power supply, or powering the board in general.

The electrical installation shall be completed in accordance with the appropriate

requirements (e.g., cross-sectional areas of conductors, fusing, PE connections. For further

information, see

Section 2.2.2).

2.2.2

3 kW FOT PFC demonstration board setup

It is preferable to use an AC supply isolated and protected against overload and short-circuit

during the evaluation test of the power board 3 kW FOT PFC (in compliance with technical

equipment and accident prevention rules).

A proper load, able to dissipate or in any case absorb and reuse the power delivered by the

system, has to be used. In the case of a resistive and dissipative dummy load, the user must

pay attention to the temperature that the load could reach and provide the necessary

equipment to avoid hot surfaces and fire hazards during the tests (fan, water-cooled load,

etc).

Caution:

Do not touch the boards and its components after disconnection from the voltage supply, as

several parts and power terminals which contain possibly energized capacitors need to be

allowed to discharge.

Hardware layout

Figure 4.

Power board 3 kW FOT PFC STEVAL-ISF001V2 (top view)

The mains input connector is present on the right side of the board. Connect a sinusoidal

supply voltage with amplitude in the range of 185 Vrms to 265 Vrms. The power source has

to be able to supply the power required by the system, according to the output load the user

intends to connect on the output port.
