Abstract :

In this paper, a modified single stage ac-dc converter using pwm scheme with field programmable gate array (FPGA) controller. This converter integrates the operation of the corrected power factor at input side and ac-dc converter operation. This ac-dc converter is made to operate with FPGA controller for regulated dc output voltage. A center tapped transformer is connected to the input through only two diodes, which results in low conduction losses. Equations and configurations are given to design for the transformer. This converter is operating with two controllers with FPGA. One controller that performs power factor correction and other controller that regulates dc output voltage. The paper explains the operation of the new converter in detail and discusses its features and a procedure for its proper design. Experimental results obtained from a prototype are presented to confirm the feasibility of the new converter.
