INTRODUCTION In recent years the usage and progress of Programmable Logic Devices (FPGA, CPLD) are increasing for the power electronic applications without microprocessors (CPU or DSP) and microcontrollers [1-2]. Complex control algorithm can be implementing for any power electronic system using FPGA processor and computational time also significantly reduced using programmable logic devices [3], but in terms of business based applications for power electronic systems are designed using microprocessor & microcontroller [4-6]. Generally to improve the output of renewable energy system or dc source, the dc-dc boost converters are employed. The relevance of dc-dc converters engross the following requirements like high step up output voltage gain, low input current and low current ripples, high output voltage and low voltage ripples and higher efficiency [7-10]. The various dc-dc converters are design with help of conventional coupled inductor, switched capacitor, clamping diodes and controlled power semiconductor device, which is controlled by duty ratio. Based on duty ratio of dc-dc converter the output voltage can be increased or decreased [11-14]. In this paper gives the procedure to generate switching pulse for dc-dc boost converter using Xilinx-ISE with FPGA processor and matlab. The hardware results for dc-dc boost converter are obtained using Spartan-6 FPGA processor. 2. DC-DC BOOST CONVERTER The dc-dc converter is electronic system which converts dc source voltage from one voltage range to another voltage range [15-17]. It attracts many researchers to boost or increases output voltage from the renewable energy systems like fuel cell, PV system and wind energy system [16]. The conventional dc–dc converters are power switching converter which innately introduces a certain amount ripple in current
