摘要： PURPOSE:To improve power factor by a method wherein an element with a function of current breaker is used for a power converter. CONSTITUTION:A deviation T between a speed command PP and the output of a speed generator PG is fed into a function generator Fa to obtain an armature current command Sc. A deviation between the armature current command Sc and an armature current from a DC current transformer CT is fed into a function generator Fd for phase angle control and a function generator Fp for pulse width control as a voltage command. A phase angle control signal and a pulse width control signal are fed into a gate control circuit GC to control the control lagging angle alpha of thyristors U2-W2 and the conductive pulse width of gate turn off thyristors GTOU1-GTOU3 composing a power converter. Meanwhile, a deviation signal T is fed into a function generator Ff obtaining a field current control command as well and a current flowing into a field winding F is controlled.

摘要： PURPOSE:To improve the power factor in wide voltage range by controlling the time width to be opened and closed during the closing time determined by the phase angle by simultaneously setting equally to the phase angle of the switching means having current breaking function. CONSTITUTION:A control delay angle alpha is set to 90 deg., a current flows through a GTOU1 and a thyristor V2 as shown in a loop 1 during the firing period of the GTOU1, and a negative current flows to the power source. At this time the GTOU1 is broken, and the GTOU2 is fired. Then, a load current flows a loop 2 but does not flow through the power source. The output voltage E0 at this time becomes zero. Accordingly, when the time duration is sufficiently shortened, the output voltage E0 and a U-phase current IL can be sufficiently reduced, thereby improving the power factor.

摘要： PURPOSE:To prevent the processing speed reduction of a CPU and to eliminate an expensive equipment by providing a means connecting the 1st control section control signal system with a CPU when no data transfer is applied between the 1st control section and the 2nd control section and separating the control signal system for the 1st control section from the 2nd control section. CONSTITUTION:When no data is transmitted between the 1st and 2nd control sections, the control signal system of the 1st control section and the control signal system of the CPU are connected to disconnect the control signal between the 1st and 2nd control sections thereby making the 1st and 2nd control sections independent by a connection control section. The connection control section makes the CPU 11 of the 1st control section independent of the data transfer processing device of the 2nd control section 2 to avoid the increase in the operation disabled state of the CPU attended with the data transfer processing and the transfer data on the 2nd memory is referenced directly by the CPU thereby reducing the data transfer processing. Thus, the reduction in the processing capability of the CPU in parallel processing is avoided and the CPU in the 2nd control section is not required to eliminate the expensive device.

摘要： PURPOSE:To eliminate the damage of a switching element by generating a pulse of necessary minimum time duration for ON and OFF of the switching element in synchronization with an input signal of chopping means. CONSTITUTION:A chopping pulse from a chopping pulse generator 11 is inputted to OR circuits 29, 43. The minimum pulse width producing circuit 33, 34 generate a pulse of necessary minimum time duration from turn ON to turn OFF of a switching element and from the turn OFF to the turn ON in synchronization with the rise of the chopping pulse. This pulse is applied to a gate pulse generator 12 which controls the switching element through the OR circuit 43.
