When in power-sending mode, the master-MCU generates sinusoidal pulse width modulation wave and sends it to the driver.
The step-down transformer transfers the medium-voltage to U1, which is the working voltage of the back-to-back converter, and the converter outputs the desired disturbance voltage waveform according to the modulation wave signal.
Figure 1 shows variations of the normalized modulation growth rate (varOmega /omega_{0}) with respect to the normalized modulation wave number (Kc/omega_{0}), when (z_ = z_ = 10).
She could build sound from its constituent parts, changing in tiny increments up to 40 parameters such as frequency and modulation, encouraging waves to beat and pulse against each other.
In Fig. 4, u is the output of the current controller G c(s), x represents one of the voltage and current states in the LCL filter, u m is the modulation wave (i.e, the PWM reference), and k PWM stands for the transfer function from u m to u inv.
The error of voltage generates a modulation wave by the regulator T(S).
At the same time, the output of disturbance voltage can be changed freely by modifying the modulation wave signal.
As mentioned earlier, by modifying the modulation wave signal of the inverter, the corresponding high-voltage harmonics can be generated on the 35 kV bus.
The average crystal structure and the modulation wave vector were firstly derived by analyzing the reflection separations induced by the martensitic transformation on the basis of the transformation orientation inheritance.
Many additional spots in the Laue pattern (Fig. 1b, far right, Figure S1 B, Additional file 1) provide the evidence of the existence of many modulation wave vectors, the directions and lengths of which do not coincide with that of the scattering vectors of the basic structure, and confirm the 2D incommensurate (misfit) layer structure of BDD with the same boron concentration.
