WEEK 7

TITLE: Designing block diagram

OBJECTIVE: 
To identified what is the operation involved in the project.

ANALYSIS/DISCUSSION: 

BLOCK DIAGRAM

The circuit that will be developed consists of two sides of power consumed, which one is low power side which consists of controller and high power side which consist of MOSFET driver and switching devices H- Bridge circuit. At the low power side the circuit use Get logic as the controller to control the overall the switching of the H-Bridge circuits. 

The purposes of the Isolator is to isolate the low power side with high power side in order to make sure the operation of the circuit going well. At the high voltage side, the powers MOSFET is a voltage gate controlled switching device which will control the switching of Gate junction by turn it on and off. The MOSFET driver is compulsory part in this driving circuit to fully turn on the power MOSFET. The purposes of H-Bridge circuit beside act as a switch it will generate a sinusoidal output current which will be used by the DC motor. The DC motor must also being supply by the High Voltage in order to make sure it operate normally. The overall project is to developed a three phase driver circuit,therefore three same type of circuit will be created.

CONCLUSION:

As the conclusion, the block diagram is successful designed and other people will understand more about this project as the block diagram help them.
