Hardware Overview
•
Demo Mode: Uses the GUI to quickly show how the board functions. All power used by the board is
provided from a single 390V DC power supply.
provided from a single 390V DC power supply.
1. Insert a pre-flashed F28027 control card into socket [Main]-H1.
2. Connect your computer to the board using a USB cable.
3. Verify the following jumper settings:
(a) Jumpers are placed on [Main]-J1, J2, J3, J4, J5.
(b) Jumpers are placed on pins 1-2 on [Main]-J7, J8.
(c) A jumper is placed on [M4]-J4.
(d) No jumper is placed on [Main]-J6.
4. Verify that no DC power supply is connected to [M3]-JP1.
5. Connect a 390 V DC power supply across [Main]-BS1, BS2.
6. Connect a load across [Main]-BS3, BS4.
•
Experimentation Mode: Uses CCSv4 to experiment with how the board functions. Two different
power supplies are used to minimize the risk of damage while experimenting. The primary and
auxiliary power rails will each use a separate power supply. This mode allows the user to verify PWM
output and ADC feedback signals before energizing the DC/DC power stage and helps protect the
MCU if a fault occurs on the primary power rail.
