Abstract - DC-DC Converters are the electronic devices used to control and supply DC voltage at the desired voltage level while transferring electric power efficiently. There are many applications involving constant DC voltage in range of 350-400. Design of boost converter is presented after analysis of the requirements. Simulation results carried out for the required operating conditions and constant output voltage. Input voltage is varied from 100 to 250V and controlling of converter is done with Proportional-integral (PI) controllers for constant output voltage i.e 400V.
Keywords-Boost converter, DC voltage, control techniques, Simulation, constant output voltage.
I. Introduction
DC-DC converters are used for controlling and condition the flow of electrical energy between two systems [1]. An important point to remember about all DC-DC converters is that like a transformer, they only change the input energy into a different impedance level but do not generate energy [2]. DC-DC converters are commonly used in applications requiring regulated DC power, such as computers, medical instrumentation and communication devices [3]. DC-DC converters are also used for traction motor in electric automobiles, trolley cars, ships, aircraft, hybrid electric cars and buses, trucks [5]. DC-DC converters can be divided into two broad categories as non-isolated and isolated converters. Boost topologies have characteristics, such as continuous input current, low input ripple current, good clamping of output diodes requiring less than half of the voltage rating of rectifier diodes [4]. The pulse-width-modulated (PWM) controlled technology has been extensively applied in controllers of power electronic products [6]. Proportional-integral (PI) controllers are widely used in industrial control systems because of the reduced number of parameters to be tuned. They provide control signals that are proportional to the error between the reference signal and the actual output (proportional action), to the integral of the error (integral action)[7].
