For wireless power transmitter systems, several DC-DC converters have been reported to enhance voltage gain using a single switch over conventional boost converters. Although the voltage gain improves the quadratic boost converter (QBC), the voltage stress on the switch and the output diode remain equivalent to the converter's output voltage. To enhance voltage gain and minimize voltage strain on the switch and output diode, a switched capacitor inductor network (SCLN) has been introduced by adding a diode and a capacitor to the QBC. Due to the superior voltage gain in SCLN compared to QBC, the voltage stress on the switch and output diode is reduced below the output voltage, however, it resembles the same as QBC. In this article, addressing the specific requirements of wireless power transmission, by substituting a diode in the SCLN with a switch, a converter known as the reduced voltage stress of the switched capacitor inductor (RVSCL) converter is proposed to further decrease the voltage stress on the switches. The steady-state gain of the RVSCL converter, considering both ideal and non-ideal model analysis, is discussed. An extensive comparison between the RVSCL and traditional converters highlights its benefits. The components of the RVSCL converter have been designed for wireless power transmitters to obtain output voltage and power of 400 V and 500 W, respectively, and its analytical performance is corroborated by simulation results.
