Main source of power dissipation for dynamic CMOS circuits is due to charging and discharging of intrinsic capacitances, commonly referred to as switching power. As switching power dissipation is proportional to the square of supply voltage, lowering the supply voltage is the most effective way to reduce switching power dissipation. However, the reduction of switching power by lowering the supp...

In this paper; we propose an event-driven simulation based approach to estimate the worst case I R drop and Ldildt inductive noise on the power supply network. The switching noise is modeled as a weighted sum of the switching currents and the rates of change of the switching currents, where the weights are respectively the effective resistance and inductance (on the P/G network) experienced by ...

Synchronous switching is one subject that have gained a great deal of relevance not only because of their potential for increasing reliability and for making a contribution to improve the overall power quality of the electric systems, but also for economic reasons. These concepts can be instrumental in minimizing the use of auxiliary components, such as pre-insertion resistors, in reducing equi...

Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...

Axial field flux switching motor with sandwiched permanent magnet (AFFSSPM) is a novel of flux switching motor. Based on the vector control method, the mathematical model of the AFFSSPM is derived and the operating performance of the AFFSSPM in the overall operating region is investigated.A novel control method for the AFFSSPM drive system, including the id =0, maximum torque per ampere, consta...

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...
