Dc-dc power converters have variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude that differs from Vg. A dc-dc converter reduces the voltage to the regulated 5V or 3.3V required by the processor ICs. High efficiency is invariably required, since cooling of inefficient power converters is difficult and expensive.  Crucial to the proper operation of the device is the condition of constant charge on the capacitor when its capacitance is reduced. This is ensured by a diode between input voltage and capacitor, the diode ensures that the charge on the load capacitance C(x) is maximum. In this work, MEMS based prototype DC-DC converter structure is simulated using SUGAR MEMS simulator.
