Authors has proposed a new method to decrease high-frequency noise at specific frequency band with modification of switching transient slope. In this paper, new voltage feedback type V DS controller (gate driver) has proposed to realize modified switching transient to increase stability. In the step-down converter applied propose V DS controller, harmonics reduction effect is obtained about 10 dB in AM radio band. Then, output voltage and switching loss characteristics was measured on the step-down converter applied proposed method. It is verified that these characteristics are same to conventional converter. In addition, the proposed method was applied to H-bridge step-down converter for DC motor drive application. It is verified that MT-PWM is able to realize in H-bridge step-down converter without any major modification through simulations. |
