Mounting, Hookup and Application Instructions

Mounting

1. Connect the driver board and the IRPT3054A module.

2. Remove all particles and grit from the heat sink and power

substrate.

3. Spread a .004" to .005" layer of silicone grease on the heat

sink, covering the entire area that the power substrate will

occupy. Recommended heat sink flatness in .001 inch/inch and

Total Indicator Readout (TIR) of .003 inch below substrate.

4. Place the power substrate onto the heat sink with the

mounting holes aligned and press it firmly into the silicone

grease.

5. Insert the two M4 mounting screws through the PCB and

power module and into the heat sink and tighten the screws to

1 Nm torque.

Power Connections

The power module pin designation, function and other details

can be obtained from the package outline (figure 7) and circuit

diagram (figure 8). 3-phase input connections are made to pins

R, S and T and inverter output connections are made to pins U,

V and W. Positive DC bus and brake IGBT collector

connections are brought out to pins P and BR, respectively.

Positive rectifier output and positive inverter bus are brought out

to pins RP and P, respectively in order to provide DC bus

capacitor soft charging implementation option. The current

shunt terminals are connected to pins IS1, IS2 and IS3, IS4 on

the positive and negative DC rails, respectively.
