--an increase in power losses of 1.26-1.43 times compared with sinusoidal current
at using steel trolley lines.
If sinusoidal PWM method is used for control, the inverter will regulate these current pulses into a sinusoidal current
in phase with the grid voltage .
To determine each of these N triangular sinusoidal currents
there is N rectangular pulse test functions with unitary amplitude .
It is achieved by using higher switching frequencies in order to form sinusoidal current
lower harmonic distortion .
The ACS 2000 design provides near sinusoidal current
and voltage waveforms making the drive compatible for use with standard NEMA rated motors.
For increasing input voltage, a DC/DC converter, which allows interaction to the AC mains, not only is used for constant output voltage but also is employed in order to perform the MPP, while inverter stage delivers a sinusoidal current
to the utility line.
The testing team noticed that the graphical waveform of the sinusoidal current
and voltage provided by the True RMS meter was not well represented by the meter.
where [I.sub.m] is the amplitude of the sinusoidal current
. For the R-FSPM motors, the motor torque is predominantly resulted from the PM excitation torque since the reluctance torque is negligible.
"If you connected them to a power supply and applied a sinusoidal current
" - an alternating current whose period is very regular - "then it would vibrate.
The DEA instrumentation applies a sinusoidal voltage across electrodes placed in intimate contact with the material being tested at a chosen frequency or multiple frequencies and measures the resulting sinusoidal current
. Changes in amplitude and phase of the response are converted into electrical properties.
The voltage on charge is forming by PWM impulses and sinusoidal current
depends by number of PWM impulses and modulation.
When a resistive load is driven by a sinusoidal voltage waveform or a sinusoidal current
waveform, the average power dissipated by the load is calculated from an RMS voltage measurement.
