In each of the legs (11, 12) of the first bridge (10), in order to increase the absolute values of reactor currents (L1, L2), the on-period of one switching element which is one of switching elements (Q11H, Q12H) on the high-voltage side and switching elements (Q11L, Q12L) on the low-voltage side is set, after which the on-period of the other switching element is set. The length of the on-period of the one switching element is set according to the control command value of a DC voltage V1. The length of the on-period of the other switching element is set to a length of time until the absolute values of the reactor currents (L1, L2) that have increased during the on-period of the one switching element return to zero.

Abstract

This optical measurement device is configured from a polarized light radiating unit 10 that irradiates an object Ob with radiated light having controlled polarization, and a polarization imaging unit 20 that images the polarization state of a measured light occurring as a result of scattering, reflection, or absorption of the radiated light by the object Ob, calculates all or a portion of the Stokes parameters of the measured light, and measures a change in a polarized component occurring between the radiated light and the measured light due to the object Ob. The radiated light having a controlled polarization state is radiated onto the object, and so it is possible to acquire object information that was difficult to measure if an object was irradiated with natural light, that is to say, unpolarized radiated light, and it is also possible to suppress noise and contrast reduction caused when radiated light having an unstable polarization state is radiated onto the object and the polarization is measured.

Abstract

Provided is a power conversion device with which it is possible to reduce switching loss and to stabilize output power. A switching mode switch (5) generates a reference signal (Dpole*) for switching the operation mode of a full bridge circuit (FB) to either a first or a second switching mode. The first switching mode is a mode in which an upper arm (Q1) and a lower arm (Q4) are switched synchronously and a lower arm (Q2) and an upper arm (Q3) are set to be nonconductive. The second switching mode is a mode in which the lower arm (Q2) and the upper arm (Q3) are switched synchronously and the upper arm (Q1) and the lower arm (Q4) are set to be nonconductive. The switching mode switch (5) adjusts the phase of the reference signal (Dpole*) so that reactive power becomes small.

Abstract

A power conversion device according to the present invention converts a DC voltage output from a DC power supply into an AC voltage in a current discontinuous mode. A current controller (6) calculates a target voltage value (VL*) between both ends of a reactor such that a value of current (Iinv) flowing through the reactor becomes a target current value (Iinv*). In the current discontinuous mode, a nonlinear compensator (701) calculates a target conduction ratio (D*) of a current sampling time by using the target voltage value (VL*), a target conduction ratio (D*) before one sampling time, and an output voltage value (Vc) before one sampling time.

Abstract

There are provided a method by which a stress history of an object can be measured with high reliability if the object, which has temporarily been elastically deformed upon receiving an external force, recovers from the elastic deformation, and a composite material containing cement as a main component, of which a stress history can be measured with high reliability without reducing the strength of the material itself and without breaking the structure. To achieve the above-mentioned advantages, the method includes the steps of: acquiring an initial value of a twin density for calcite particles contained in an object to be measured that is elastically deformable upon receiving an external force; and measuring a history of stresses received by the object to be measured on the basis of a difference from the initial value in respect of the twin density for the calcite particles after the object to be measured receives the external force. The composite material includes calcite particles, for which a twin density is known and which are mixed to be distributed in the material, partially replacing an aggregate of the material.
