H-Bridge, 3-Phase motor, MOSFETs, Pulse With Modulation (PWM) ... The Current continues to the winding in phase U then goes through the phase V winding. From there current goes through the MOSFET in phase V on the low side. Then the timing from the microcontroller will make the current flow through the different phases at different times indicated in Figure3. Caution the timing must be correct ...

The per-phase equivalent circuit is shown below in Figure 3.8 . Figure 3.8 Per-Phase Equivalent Circuit. In the above step, the total current is obtained by summing the individual currents through the three loads. For loads 1&2, we use the expression , and for load 3 the current is determined using. In the distribution line, In each load, Check : Example B 3.3. A balanced 230 volt (rms) three ...

In Fig. 3, the period of each waveform is 16.7 msec, which corresponds to the 60 Hz frequency of the alternating current. Once I have the data shown in Fig. 3, I can calculate the difference between any two of the voltages. I can do the calculation within Logger Pro, or I can first export the data to another program, such as Excel. Figure 4 is a Logger Pro graph of two of the phase voltages ...
