摘要： PROBLEM TO BE SOLVED: To provide a sensor-less magnetic bearing control device having a simple system structure without requiring a special digital arithmetic processing.
SOLUTION: A bias voltage source 12 for supplying a bias current required to maintain the linear characteristic of electromagnets, and a control current source 7 for supplying the exciting current required to control a rotor to be floated for support at a desirable position, while overlapping with the bias current from the bias voltage source, are connected to the electromagnets 10 and 11 forming a magnetic bearing. The exciting current output from the control current source is supplied to the pair of electromagnets, which are arranged opposite to each other, at an opposite duty ratio by controlling the magnetic bearing control voltage source to modulate an amplitude of the pulse. The duty ratio is controlled so that impedance of each of the pair of electromagnets, which changes in response to position of the rotor 13, becomes equal to each other.

摘要： PROBLEM TO BE SOLVED: To provide a photovoltaic power generation control device that carries out follow-up control on maximum power point with high accuracy by detecting a minute change in power even when a low-resolution AD converter is used. SOLUTION: A photovoltaic power generation control device is characterized by that a control circuit 44 flips a switch 41 to an output A side of a voltage detector 8 and a current detector 9, and gives a low frequency ripple component to the operation voltage of a solar power 1 while increasing a modulation degree D with a predetermined change width d to start searching for the maximum power point from an open voltage side. The operating point vibrates near the maximum power point, and when the value of power obtained after updating the modulation degree gets smaller than the value of power output by a power detector 43 before updating the modulation degree, it is determined that the power has passed the maximum power point and the switch 41 is flipped to the output side of amplifiers 23, 24 and follow-up control on maximum point continues.
