The four compensation capacitors are divided into parallel capacitance team and series capacitance team, and the work mechanism of the compensation capacitance on the output power, efficiency and the terminal voltage of the system are deeply analyzed. Then, the optimization approach based on Bayesian is given.
After the optimization of the capacitance team, the efficiency of system is improved from 83.53% to 85.81% in full alignment, and from 72.52% to 78.54% under 100 mm offset, which is improved by 2.28% and 6.02%, respectively. TABLE 4. Comparison of the results of different validation methods
Similar to the current stresses across coupling coils, the voltage stresses over compensation capacitors are obtained and tabulated in Table 3. In general, the voltage stresses of LC/CL topology are lower than those of SS. Table 3. Voltage stresses over compensation capacitors for LC/CL and SS compensation topologies
The simulation results show that under similar load voltage fluctuations, the proposed scheme uses 9.4 mF output capacitance and four 100 µF switched capacitors. By contrast, the conventional scheme uses 18 mF output capacitance.
Circuit Models Of Capacitor And Inductor With Parasitic Resistance. The system efficiency of four SP-based compensation topologies can be derived from Equations (49) and (50). Taking the LCCL compensation topology as an example, its AC−AC efficiency is calculated as where GV is equal to Cc / CS2, and C ′ a, C ′ c are expressed in (40).
