System Components
This reference system is made up with three daughter board. They are:
Power Board
This board contains the EMI filter stage and an AC-to-DC module. The AC-to-DC
module can output a stabled 15V (15W) power line. It will be transformed to two 5V
power lines through line regulators, one is for MCU system and another is for
cooling fans. At the same time, isolated 5V power line comes from the 15V line by
isolated DC-to-DC, and another isolated 5V is for isolation communication device.
Inverter Board
There are PFC stage and Inverter stage, as well as a full bridge rectifier module
provided for selection when the user doesn't need PFC stage.
DC-Link Board
DC-Link Board can make smoothly 100Hz half-sine-wave power and it can provide
to DC bus through three electrolytic capacitors.
The input and output cables should be with the minimum current rating of 10A.
Figure2-1 shows the connection of the boards.
