When the mains voltage is near its instantaneous peak of the cycle, that is near 220V (for a 220V) mains input, it's in the strongest zone in terms of voltage and current, and if a capacitive power supply happens to be switched ON during this instant, the entire 220V can be expected ...
The power supply circuit used for powering this array is derived from a high voltage capacitor, whose reactance value is optimized for stepping down the high current input to a lower current suitable for the circuit. The two resistors and a capacitor at the at the positive supply are positioned...
The calculations of the converter, the generator (equipped with a diode bridge) as element of the power system supply joint, and the load replaced by resistance are verified with PSIM software.doi:10.2478/v10047-012-0021-5Suskis, P.
The loss calculations for inductors are carried out by ignoring the ripple in the inductor current through the leakage resistances r L 1 , r L 2 , and r L 3 . 𝑟𝐿1, 𝑟𝐿2, and 𝑟𝐿3. Inductors L 2 𝐿2 and L 3 𝐿3 have the same design values; hence, their parasi...
By using these time calculations and by considering that the main objective of the DCM-232 topology is to reduce the CMC by decoupling the DC sources, a simple way to obtain a constant common mode voltage for different vector sequences is proposed. Considering the active vectors given in Table...
The performance of the proposed transformerless inverter is evaluated in terms of the efficiency using the power loss calculations mentioned in Section 4 and compared with the simulated results obtained using the PSIM thermal module. There is a slight difference between the simulation and theoretical ...
and transients appear in the measured voltage due to the capacitance component between the system and the line-to-ground. IMD can be largely categorized into two groups depending on the injected wave. The measurements and calculations by IMD are conducted by injecting either a sine wave or a sq...
Nowadays, the leading fast-charger schematics are based on different advanced switched-mode power supply topologies: LLC resonant converters with soft switching [5,6], phase-shift converters [7], two and three-level, three-phase, full-bridge direct current–direct current (DC–DC) converters [8...
