The resonant power conversion having many advantages over conventionally adopted pulse width modulation that includes a high efficiency, low electromagnetic interference, small volume, low switching losses, and light weight of components due to a high switching frequency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This paper presents the doubly loaded r...

High power factor, high frequency single stage single switch resonant inverter for the application of high frequency applications is presented in this paper. The power circuit is designed with a power factor corrector with single-switch current-fed high frequency resonant inverter. Number of switches used in conventional ballast circuits is reduced in single switch approach. SEPIC (Single ended...

Today’s Microwave ovens are often equipped with inverterized MW generators; compared with old style appliances, the magnetron is no more driven by a bulky ferro-resonant power supply, but by an electronic inverter, lighter, more efficient and, moreover, able to modulate the MW power, at least to a certain extent. The electronic power supply is generally designed around a resonant inverter which...

Quasi−square wave resonant converters also known as Quasi−Resonant (QR) converter are widely used in the adaptor market. They allow designing flyback Switched−Mode Power Supply (SMPS) with reduced Electro−Magnetic Interference (EMI) signature and improved efficiency. However, as the switching frequency of QR converter increases as the load decreases, the frequency must be limited. In traditiona...

Modular multilevel converters (MMCs) have become increasingly interesting in dc-dc applications, as there is a growing demand for dc-dc converters in high voltage applications. Power electronics transformers (PETs) are commonly used for high step-down ratio dc-dc power conversion, with high power rating and efficiency achieved. However, this arrangement requires a large number of high isolation...

A novel Inductive Contactless Energy Transfer (ICET) system is presented in this paper. The energy is transferred using a rotatable air gap transformer and a power electronic converter. To minimize total losses of the system a series resonant circuit is applied, assuring zero current switching condition for IGBT power transistors. The analytical expression of the transfer dc voltage gain is giv...

Multichannel resonant DC/DC converters have recently been popular in diverse fields, where multiple output voltage levels are required, such as supplying multilevel inverters. This paper is devoted to present the new member of a four-channel converter family, having consisted till now step down well step-up/down configurations. The capable realizing power flow amongst two input and four channel...
