5. Power Circuit for P.W.B
•
Fig. 5-1 shows the power circuit for P.W.B.
•
In the power circuit for P.W.B., power supply for microcomputer, peripheral circuits
Microcomputer
, and IPM driver
circuit and, as well as DC 35V, are produced by switching power circuit.
•
Switching power circuit performs voltage conversion effectively by switching transistor IC1 to convert
DC 330V voltage to high frequency of about 20kHz to 200kHz.
