The topology of parallel connected PCS for EV charge–discharge and storage integration station is shown in Fig. 2, where V bat is the battery voltage, L dc and C dc are the dc-link filter inductor and capacitor, L 1 , L 2 and L are the ac filter inductors, and C is the ac filter capacitor.
Furthermore, losses are minimized when the two sources have equal voltage. Parallel systems of interconnected sources operate optimally when their voltages are identical, and their shared current behaves as if they were connected to a single source. Two parallel DC sources feed a DC load.
Various academic articles have classified methods for controlling parallel inverters. These studies have divided control systems into two categories: centralized and decentralized 1, 3, 4, 5. The modules in parallel inverter systems are frequently dissimilar, which leads to an imbalance in the distribution of load current.
PSO is employed in 14 to calculate the losses in parallel inverters by examining the efficiency curve fitting of a single inverter. 15 creates mathematical models to evaluate the reliability of paralleled inverters, utilizing different topologies and control methods.
These studies have divided control systems into two categories: centralized and decentralized 1, 3, 4, 5. The modules in parallel inverter systems are frequently dissimilar, which leads to an imbalance in the distribution of load current. Therefore, certain modules may be carrying an excessively large current.
First step: Fig. 2 shows a DC circuit with two discrete sources (V 1 and V 2) supplying the DC bus through two lines with resistances (R 1 and R 2). To achieve constant load voltage (V L) and deliver Power P with minimal losses, Eq. (21) can be optimized using Lagrange Eq.
Parallel resonant LC circuit. A parallel resonant circuit in electronics is used as the basis of frequency-selective networks.

We know that when two resistors are connected in parallel then effective resistance is the sum of reciprocal of the resistances of the individual resistors. Consider a parallel LC circuit with R L and R C as the resistance of the inductor and capacitor respectively. Thus impedance or net resistance of parallel LC circuit is given by: 1/Z = 1/R ...
A parallel RLC circuit contains a resistor (R), an inductor (L), and a capacitor (C) connected in parallel. Resonance in a parallel RLC circuit occurs when the reactive effects of the inductor and capacitor cancel each other out, resulting in a purely resistive circuit.

Under light load conditions, the phase-shifted full-bridge (PSFB) converter often has difficulty in realizing the zero-voltage switching (ZVS) of the lagging-leg by relying on the energy of its resonant inductor; however, for the series-parallel PSFB converter applied in high-power applications, the lagging-leg still has the problem of difficult realization of ZVS.
