    摘要: A photovoltaic power generation controller, in which minute power change is detected even with a low-resolution AD converter, thereby being capable of performing maximum power point tracking control with high accuracy, is provided. In the photovoltaic power generation controller of the invention, a control circuit 44 shifts switches 41 to respective output A sides of a voltage detector 8 and a current detector 9; gives a low-frequency ripple component to an operating voltage of a solar cell 1 while increasing modulation factor D by predetermined variation width d, to start maximum power point search from an open circuit voltage side; confirms a maximum power point passage when: an operating point oscillates in the vicinity of the maximum power point; and a power value, which is output by a power detector 43, after update of the modulation factor becomes smaller than a power value before update of the modulation factor; and switches the switches 41 to respective output sides of amplifiers 23 and 24 to continue the maximum power point tracking control.

    摘要: An energy-saving magnetic bearing device with no bias current for making the relation between the excitation current and the magnetic force of the electromagnet linear is provided. In a magnetic bearing device for supporting a rotor 1 serving as the magnetic piece in a levitating state allowing free rotation at a specified position by the magnetic force of a pair of electromagnets 2, 3, the electromagnets 2, 3 are constituted to interpose the rotor 1 and face each other. A driver 204 is a PWM (pulse width modulation) type driver for controlling the excitation current in the electromagnets 2, 3 by modulating the pulse width of a voltage driven at a specified carrier frequency fc, and includes a resonator means for electrically resonating at a frequency equal to the carrier frequency fc. When an excitation current flows in either one of the pair of opposing electromagnets 2, 3, then the other magnet is regulated so that the DC component in the electromagnet excitation current is zero, and a voltage is applied via the resonator means to the electromagnet whose DC component in the excitation current is discharged to zero.
