2 Application and handling instructions

Please provide static discharge protection during handling. As long as the board is not completely

assembled, the input terminals have to be short-circuited. Persons working with devices have to wear a

grounded bracelet. Any synthetic floor coverings must not be statically chargeable. Even during

transportation the input terminals have to be short-circuited using, for example, conductive rubber.

Worktables have to be grounded.

The inputs of the board are sensitive to over-voltage. Voltages higher than VS+0,3V or below -0,3V

may destroy these inputs. Therefore, control signal over-voltages exceeding the above values have to

be avoided.

3 General description

3.1 Overview

SKiiP®3 subsystems are connected in parallel to achieve higher output current. The SKiiP®3 Parallel board is

designed for connecting up to four SKiiP®3 subsystems to one controller. The example of SKiiP®3 Parallel

board application is shown in the Figure 1. The switching signals from controller are routed to all paralleled

devices. Analogue signal measurements and error siganls from the paralleled devices are converted and

transferred to the controller.

Figure 1: An example of SKiiP®3 Parallel board application

For an EMI-safe transmission of the switching- and error-signals, there is the possibility to mount an optional

fiber-adapter F-Option board SKiiP®3 on top of the SKiiP®3 Parallel board. No mechanical housing is required

since the board is directly mounted on a metal frame inside the cabinet.

All different SKiiP®3 Parallel board product variants are based on one common board-layout but do have

different number of connected SKiiP®3 subsystems:

Type 1: Board setup for paralleling of two SKiiP®3 GB systems 1200V/1700V with and without F-Option

(using connector X3/X4 & vertical connector X1)

Type 2: Board setup for paralleling of three SKiiP®3 GB. systems 1200V/1700V with and without F-

Option (using connector X3/X4/X5 & vertical connector X1)

Type 3: Board setup for paralleling of four SKiiP®3 GB systems 1200V/1700V with and without F-

Option (using connector X3/X4/X5/X6 & vertical connector X1)

The pollution degree class 2 and IP00 shall be considered for the SKiiP®3 Parallel board.

The main functions of the SKiiP®3 Parallel board are shown in the Figure 2. They are:

24V routing from supply connector X2 to all four SKiiP®3 DIN41651-connectors X3/X4/X5/X6

Generation of +15V for F-Option-Board. It will be supplied by the controller connector X1 (+15V)

Monitoring the +15V; -15V; in case of failure the ERROR signal will be activated.

Providing the maximum temperature value or maximum DC-link voltage of all connected SKiiP®3

subsystems (Analogue Out, Pin 12 / connector X1)

X1)

Routing the TOP/BOT switching signals from the controller (Digital IO, Pin 4 and Pin 2 / connector X1)

to all four SKiiP®3 connectors X3/X4/X5/X6 (incl. Short-Pulse-Suppression, TOP/BOT-Interlock and

min. Pulse-Time)

Linking the error and temperature error signals from the connected SKiiP®3 subsystems to the

corresponding error signal (Digital IO, Pin 3 and Pin 5 / connector X1)

Providing grounding option via metal screws or over the supply connector X2 for the shield of all four

SKiiP®3 connectors X3/X4/X5/X6.

8 Digital Input/Output Signals

8.1 TOP/BOT switching signals

The main purpose of SKiiP®3 Parallel board is the routing of the TOP/BOT switching signals from controller

connector X1 to all four SKiiP®3 connectors X3/X4/X5/X6. The routing includes the following tasks:

- Logic Level detection of TOP/BOT signals;

- Short pulse suppression and extension of TOP/BOT signals (See Chapter 13);

- Generation of Interlock time for all connected SKiiP®3 (See Chapter 11 for detailed information and

corresponding data sheet for tTD time value).

The characteristics of switching signal can be found in the Table 4.

Table 2: 24V Power supply connector pin assignment

Please note: Use for 24V power supply wire size of 2.5 mm2to withstand max. nominal current of 8A.

The minimal possible supply voltage on SKiiP®3 Parallel board is therefore 19,2 V, which should be

measured at SKiiP®3 Parallel board input, not at controller output (voltage drop on connection cable).

Please note: Power supply cable should be twisted or screened to enhance the EMC robustness.
