| Abstract |
This paper proposes an AC voltage regulator for resistive loads using the PWM technique and magnetic flux distribution. The load voltage can be controlled using one switching element( MOSFET) and three limb magnetic circuit. The proposed regulator depend on the PWM technique and control the magnetic flux distribution in the magnetic circuit sections.The suggested regulator gives smooth variation of the load voltage and nearly sinusoidal current at the supply terminals with minimum harmonics. The power factor at the supply terminals is nearly unity over the control range of the load voltage. Equivalent circuit of the regulator is proposed. The computed results are compared with those obtained experimentally using a test model, where good agreement is achieved. |
