制御される。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method and apparatus for generating a control voltage for a DC elevator 17 by means of a semiconductor switch, here connected to an AC power supply. The DC motor is controlled in four quadrants by the constant voltage earthwork real key accumulator and its charging means.
直流モータの特性は質の点でエレベータ技術では如何な

いことと、速度制御が正確であることとを指す。この理
由で特にギヤレス高速エレベータは専ら直流モータな用
いて作られている。The characteristics of a DC motor are superior in terms of quality to any AC motor in elevator technology. Quality here refers to the absence of vibration and accurate speed control. For this reason, gearless high-speed elevators in particular are made using direct current motors exclusively.
そして高速エレベータ技術では、直流モータの制御に４

A quadrant silisque bridge is used.

である。This has replaced the classic Ward Leonard technique. This new technology is promoted by its high efficiency, for example. However, there are drawbacks, such as poor power factor, large current at start, and harmonic 1 waves entering the power supply. What's also alarming is that if the power supply fails, the fuses may blow, trapping people in the elevator from floor to floor.

得ていする。こｎは成る利点を有する。(Prior art) In order to eliminate the drawbacks of stiffness, for example, as seen in Finnish Special Patent Application No. 888051 and No. 88802, a type temperature voltage produced by rectification is used in an energy storage device. It has been devised to extract the drive energy for a DC motor from this, in which case the control signal for the DC motor is derived from the constant voltage of the energy storage device by means of pulse width modulation.This has the following advantages.
一必要な定格電源電力が低い。蓋し、エレベータ−が停
止している時でも工弔ルギーがエネルギー蓄積器に入る
からである。そしてこのエネルギー蓄積器の充電電流は
かなり小さいから、力率と高調波は問題にならない。- The required rated power supply is low. This is because engineering energy enters the energy storage even when the lid is closed and the elevator is stopped. And since the charging current of this energy storage is quite small, power factor and harmonics are not a problem.
−スターティング電流は電源に問題を課さない。- Starting current does not pose a problem to the power supply.
電源はエネルギー蓄積器に一定の充電電流を供給するだ
けですむ。The power supply only needs to supply a constant charging current to the energy storage device.
一エレヘーターには何時も（エネルギー蓄積器から）電
力が供給される。このため電源が故障してもヒユーズが
とんで、人を閉じ込めることがない。One electric heater is supplied with power (from the energy storage) at all times. Therefore, even if the power supply fails, the fuse will not blow and trap people.
最も良く知られている定電圧ｑ］エネルギー源は蓄電池

ギーが大きく、容量も大きく、保守が容易である。The most well-known constant voltage q] energy source is a storage battery. For example, a flywheel can be used instead of a storage battery, but a flywheel has a higher instantaneous energy, a larger capacity, and is easier to maintain than a storage battery.

It represents an electric appliance, which allows energy to be stored in the energy storage device 2 according to the demand. The power supply connection is represented by the voltage U, but it can also be single-phase. This is because the drive system of the present invention requires only a very small amount of current because the energy accumulator 2 has an equalizing effect. Charger 1 can be turned on and off in the usual way, but this will not be discussed in detail here.

向を有する整流電圧を表わす。The voltage waveform of FIG. 4 is clearly different from the known voltage waveform provided by a sinusoidal voltage source. This n is clearly obtained by comparing the waveforms in FIGS. 4 and 5. In FIG. 5, as in FIGS. 2 and 8, the voltage waveform of a thyristor rectifier rectified by a sinusoidal voltage source is calculated. The phase-to-phase voltage in FIG. 5b is derived from the phase voltage R3T in FIG. 5a. Therefore, when the firing angle is further given, the terminal voltage of the motor can be derived. This can be seen in FIG. 50 as derived from the voltage waveform of a six-phase rectifier operating on a sinusoidal power supply for a given firing angle. The voltages of FIG. 5C can be compared to the voltages of FIG. 4d, which in the case of the present invention represent rectified voltages having approximately the same direction.
