Switched Mode Power Supplies for DC to DC Conversion
ثبت نشده
چکیده
Introduction The widespread use of battery operated portable devices such as cell phones and laptops has created the need for DC to DC conversion power supplies such as switched mode power supplies. According to an Electric Power Research Institute (EPRI) study [1], the amount of electricity that flowed through switched mode power supplies in 2004 was “6% of the national electric bill”. The prominence of distributed energy sources such as solar photovoltaic systems, which produce DC power has created a demand for DC to DC converters. This paper briefly reviews the technology used in switched mode power supplies for DC to DC conversion for transferring energy from input to output. The paper will focus on the use of switched mode DC to DC converters to increase or decrease the output voltage as compared to the input voltage and for providing impedance matching.

Power MOSFETs first started appearing in 1976 as alternatives to bipolar transistors. These majority carrier devices were faster, more rugged, and had higher current gain than their minority-carrier counterparts. As a result, switching power conversion became a commercial reality. AC-DC switching power supplies for early desktop computers were among the earliest volume consumers of power MOSFET...

Resonant mode conversion techniques are used nowadays to improve pulse width modulated dcdc converters. Moreover the quest for ever smaller 50 to 500 watts dc-dc switching supplies has led to the development of circuits that operates in 500 KHz -1 MHz range and above. Since the parasitic elements that normally present in a power circuit can be very significant at this frequency, most of the wor...
