摘要： An electric current sensor for sensing an electric current flowing through a conductor comprises a single hall element having a magnetic-flux sensitive surface, and an angle adjusting mechanism. The angle adjusting mechanism changes an angle between the magnetic-flux sensitive surface and the direction of a magnetic flux induced by the electric current flowing through the conductor. The magneto-electric conversion element outputs an electric signal in response to a magnetic flux density at the magnetic-flux sensitive surface. The electric current sensor detects the electric current flowing through the conductor based on the electric signal output from the magneto-electric conversion element whose magnetic-flux sensitive surface is oriented with respect to the magnetic flux at a selected angle.

摘要： A power converter directly converting an AC voltage into an AC voltage of any desired magnitude and frequency by turning bidirectional switches ON and OFF without employing any energy buffer, where the peak values of output phase voltage command values are limited, to bring the amplitude of an output line voltage to, at most, 0.866 times the amplitude of the supply line voltages. By way of example, the peak-value limit of the output phase voltage command values is set so that the maximum value of the output phase voltage command values becomes, at most, 0.75 times the maximum value of supply phase voltages, while the minimum value thereof becomes, at least, 0.75 times the minimum value of the supply phase voltages. This control method for the direct power converter dispenses with an expensive dedicated motor, and permits a reduction in cost of the control apparatus as a whole.

摘要： A current sensor 73 detects a current flowing through a first buss bar 11. When a current value detected by the current sensor 73 became equal to or greater than a threshold current value, a CPU 74 outputs a driving control signal to a driving circuit 77, and the driving circuit 77 operates an, ignitor 29 through a second substrate 65 and a terminal 50. Therefore, the ignitor 29 ignites, a second projection 41 is melted by heat of a heating agent 27, a compression spring 34 is expanded and a thermite case 26 jumps up. Thus, electrical connection between the thermite case 26 and the first and second buss bars 11, 19 is interrupted. Further, since an outer container 61 in which the current sensor 73, the CPU and the driving circuit 77 are accommodated is integrally assembled with the cap 14a and the resin case 14b in which the thermite case 26, the ignitor 29, the compression spring 34 and the second projection 41 are accommodated, non-operational state of the ignitor 29 due to disconnection of electric wire is not generated.
