The DC-CT transducer operates like an AC current transformer, with primary and secondary windings linked by a shared high permeability core. Similar to other closed-loop methods, our technology consistently gauges the remaining magnetic flux in the core, arising from the variance between the primary...
The inductor current loop is shown in Fig. 6. Figure 6. Boost converter inductor current loop From the reference value of the current and its measured value, The RST current controller block will calculate the duty cycle as explained above. Voltage control loop The output voltage loop was...
The principle of operation of the converter can be explained by the idealized inductor voltage and current waveforms illustrated in Fig. 4A and B, which were drawn in steady state conditions, ignoring the switching ripple in the output capacitor voltage, i.e., v0(t)≈Vo (Erickson and Maksimo...
transformer102as explained in FIG. 1. The sensor202senses the DC components present within the transformer102and transmit the bipolar voltage signal to the DC component controller204through the connection108. The bipolar voltage signal is a measure of presence of DC components in the load current ...
as explained by Fujitsu semiconductors12. For the shipboard of 1 MW motor drive in13and smoother current with low ripple, converter switches should function at a greater frequency to decrease the current and voltage ripples. The important thing is decreasing switching losses for similar frequencies,...
output. The circuit contains a transformer with a centre tapped primary with the tap connected to one terminal of the direct current source. The outer terminals of the primary are connected to the collectors of the switching transistors. The secondary is connected to a rectifier and then to a ...
In this regard, a detailed review of power converters and the current state of the art, including bidirectional, resonant, and multilevel converters, is explained in detail by [21]. In this study, the authors provide the advantages and disadvantages of each. Consequently, the authors recommend ...
The anti-parallel body diode of the switches S1 and S2 conducts before it starts conducting current through it. It results in ZVS on of the switches. It verifies the design of the converter explained in Section V. Figure 12 ZVS condition of switch S1. Full size image Figure 13 ZVS ...
