Design buck converter for 12Vdc to 6Vdc

Abstract

A switched mode power supply (SMPS) or switching regulator, efficiently converters a DC voltage level to another DC voltage level, via an intermediate magnetic (inductor) storage or transfer stage, such that a continuous, possibly constant, load current flows, usually at power levels below a few kilowatts. DC-DC Converters are needed because unlike AC, DC can’t simply be stepped up or down using a transformer. In many ways, a DC-DC converter is the DC equivalent of a transformer. The purposes of this project were design and analyze the performance of conventional buck converter in term efficiency, low power loss and high speed switching. In simulation, PSIM software used to design of circuit conventional buck converter. From result of simulation, lastly develop the hardware circuit of conventional buck converter. Pulse width Modulation (PWM) used as pulse width modulation in generate pulse trigger to switching in circuit.
