This paper compares the efficiency of a modified wireless power transfer (WPT) system with a current-fed dual-active half-bridge converter topology and a complete bridge converter topology for a current-fed resonate compensation network with current sharing and voltage doubler. Full-bridge topologies are widely used in current WPT structures. The C-C-L resonate compensation networks for dual-active half-bridge converter and full-bridge converter topologies are built in this paper on both the transmitter and receiver sides. Due to higher voltage stress around inverter switches, series-parallel (S-P) tanks are not recommended for current-fed topologies because they are not ideal for medium power applications. A series capacitor is connected to reduce the reactive power absorbed by the loosely coupled coil. As a consequence, the C-C-L network is used as a compensation network. Dual-active half-bridge topology is chosen over full-bridge topology due to the system’s component count and overall cost. Soft-switching of the devices is obtained for the load current. The entire system is modelled, and the effects are analysed using MATLAB simulation.

Rhabdomyoma is one of the commonest cardiac tumor detected in prenatal ultrasound. Though its benign and self-limiting, it has a strong association with tuberous sclerosis, and hence needs thorough evaluation not only of the fetus but of the parents for signs of tuberous sclerosis. When isolated, fetus with rhabdomyoma needs to be only followed up for any cardiac complications associated with the mass and delivered. How to cite this article Ganesh C, Sridhar A.
