Power Supply
Power Supply
The power supply source must be 110V AC to 230V AC (50/60 Hz) on J1 connector.
Three differents voltages are generated from AC source to power the board.

LED1 is always lit when VBridge power is applied to ATAVRMC200.
During microcode debugging phase, the user must power the board directly with
VDC= 48V DC through J1 connector (PH and N connection), it will allow to check the
signal on oscilloscope and use DebugWire interface (J3) to program and debug micro-
code for AT90PWM3 part.
Warning: When using DebugWire or ISP interface through J3 connector for debugging
or programming, board must not be powered with 110-220V AC source but only with
48V DC.
Figure 3-2 . Power supply Connector
VDC = 325V DC (with 220V AC as input source) for motor phases
VBridge = 15V DC for drivers control.
and VDD = 5V DC for cpu power supply.
