3.6 Controller Board
1) Power AC input & DC rectification/smoothing
[AC power – Fuse – NTC – LPF – Bridge Diode]
 Forming of inverter operation power by radio
wave recification of AC power
 B/Diode: 4A, 600V

Smoothing condenser for motor output:
220uF/400V
 Prevention of inrush current – NTC_10D-15
2) IPM [Intelligent Power Module]
 Forming of motor control signal from
MICOM - Failchild FNB41560
3) Control Part [MICOM]
 MICOM for system control
 Flash memory & RAM insided 16bit MICOM for high-speed processing by
simplifying of circuit - working clock frequency 10Mhz (inside x 4)
 Microchip – dsPIC30F4011
 Control of external in-output and communication with display
4) Display Part
 Control function key and display by communication with main control chip
 Microchip – PIC16F917
5) Door Control [Solenoid]
 Operate by supply of DC100V voltage and current in 0..5 sec when the ‘Door’
button pressed.
 Door switch
6) Producing of inverter power
 Supply power of IPM and MICOM from SMPS
 Input: 220V / Output: 12v, 15v, hi-dc[311V_DC], 5v
 Trans & PWM control
 Smoothing condenser for power supply of control part: 47uF 400V
7) Motor [AC220V 65W]
 Motor on 3Phase operating with setting data by input of motor output voltage
from IPM
 RPM sensor
 Motor temperature sensor
