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...

The inherent performance advantage of power MOSFETs makes their use very attractive in switched mode power supplies. The fundamental advantage of the power MOSFET is the operation at fast switching speeds and high frequencies. Higher operating frequency allows further reduction in the size of the filter and magnetic components. The recent introduction of Fairchild Semiconductor’s QFET power MOS...

Present complexity of System on Chip (SOC) has brought new challenges in low power design and testing. This shows that huge test pattern and its corresponding switching activity are one of the major problems. Due to this large number of test patterns the data transition time is also increased. More switching is also proportional to more number of transitions. This paper considers the problem of...

Two generic configurations of forced commutated PWM converters, i.e. voltage source inverters and current source inverters, have been proposed as advanced reactive power compensators'.
