One Cycle Control of Tapped Inductor Boost Converter with Reduced Ripple Current

One of the main drawback of switch mode power supplies are due to their high frequency switching operation, draws a substantial amount of input ripple current. Such ripple current manifests itself as Electromagnetic Interference (EMI) and recovery problem of diodes.  To overcome this difficulty, high value of inductance is necessary but due to practical limitations a ripple current reduction circuits are needed. This paper presents a new Ripple Current Reduction Network (RRN) using tapped inductor at the input of the boost converter with high conversion ratio. This converter also provides continuous input current and reduces the size and weight of the converter compared with the Conventional Boost converter. Boost Converter close loop using one cycle control is presented in this paper. In order to show the system stability, a step response is applied at the load, with 36 V input, 50V/10A output operated at 100 KHz is done using MATLAB Software. One-cycle control is used to generate the gate pulses. Simulation results convey the operatability of the converter structure.
