Dynamic characteristics of movable electrode in MEMS variable capacitor using ANSYS software are studied. It is discovered that significant contribution to the vibration system damping is introduced by squeeze-film damping between serpentine spring arms. It is found that the vibration amplitude is inversely proportional to the stiffness coefficient and directly proportional to the number of the arms. At the same time, the amplitude is inversely proportional to damping ratio and to the arms number too. In the studied case the elastic force is strongly suppressed by the damping force.

An inverted GaAs solar cell structure has been grown with the MBE method. Together with the substrate, the structure was glued to a polymer film of polyethylene terephthalate (PET film) by means of epoxy resin. After the removal of the substrate, the contact platforms were created and the light window was opened. Research of the solar cell photovoltaic properties was conducted at non-concentrated sunlight with the AM 1.5D spectrum. The obtained effciency equal to 16.65%, taking into consideration the absence of the antireflection coating and a grid of contacts on the face of the solar cell, says about its high degree of efficiency.

The questions of new generation electrical equipment design for future power supply systems, which may be required on the board of unmanned aerial vehicles, helicopters, training aircraft are discusses in this paper. The topology of DC power supply channel with specialized alternators are proposed. The ways to reduce weight and improve the reliability of the rectifying devices are discusses. The scheme of controlled multipulse rectifier based on a single winding saturation inductor is proposed. The results of the weight, size and energy calculations of the proposed rectifier topology at input voltage source frequency variation are presented. The simulation results of proposed 18-pulse rectifier model are given in transient modes at variations of the load current and power supply voltage.

The “inverted pendulum - cart” system, consisting of object and two regulators, is described by the discrete equations in the state space. The case when unknown parameters are in the state matrix and the management matrix is considered. The calculation technique of Fischer in-formation matrix in the steady state is used for the object parameters specification. The offered approach is actual and useful in engineering calculations.
