EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC MOTOR
The project ‘’EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC
MOTOR’’ is used to varying Speed of The dc motor. It is need a DC to DC converter
is a Circuit Which converts a source of direct current (DC) from one voltage Level to
Another.
Linear regulators output can only in low in low voltage From the Input.
They are very inefficient if the voltage drop is large and the Current high as they
dissipate as heat, a power equal To the product of the output current and the voltage
drop; Consequently are not normally used for large-drop high-current Application. It
is practically if the current is low, the power Dissipated being small, although it may
still be a large fraction of The total power consumed. Simple regulator power supply
used For higher currents. A transformer generates a voltage when Rectified, is a little
higher than that needed to bias the linear Regulator. A High frequency MOSFET as
the power electronics switch, It reduces switching losses. A 230V, 3000 rpm D.C
loads to Demonstrate the converters application in speed control. The simulation Of
the code where done in keil IDE pack. A second Module remote Control machine by
using the 8 relays. It is to be control 8 machines Remotely.
