Fullwave controller rectifier for Ward Leonard system / Kamal Mat Lik

Ward Leonard System which makes used of an AC drives as a prime mover for a DC generator, which in turn is used to supply a DC voltage to a DC motor. The armature voltage of the motor can be control by varying the field current of the DC generator. Ward Leonard concept is being used for speed and position control of DC adjustable speed drives from fractional horsepower portable tools to sizes, in such application as machine tools. The Hmitations are imposed by the speed and horsepower capabilities of the DC motor. The objective for this project is to improve Ward Leonard Speed Controller System by using f uil wave phase angle control system. The con verte r circuit nas been designed and test successfully. The output from the project is full wave at the load. In this works, concentrate the full wave controller to replace from Mr. Rezal done at last year. His done the half wave controller. This project focus only on the phase controlled converter systems.
