Abstract :
A modification in the electrostatic MEMS converter has been done in order to increase its output power. This modification is done by adding the parallel constant capacitor (Cpar) with the converter capacitance. First, a simulation has been done to check if this capacitance is constant with the applied voltage. After that, the effect of adding this capacitance on the output power of the converter has been investigated. An increase in the output power of the converter has been observed due to this effect.
