In this work, we derive general conditions to achieve high efficiency cascaded third harmonic generation and three photon parametric down conversion in Kerr nonlinear resonant cavities. We employ the general yet rapid temporal coupled-mode method, previously shown to accurately predict electromagnetic conversion processes in the time domain. In our study, we find that high-efficiency cascaded t...

Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...

We describe a theoretical analysis of the nonlinear dynamics of third-harmonic generation →3 via Kerr 3 nonlinearities in a resonant cavity with resonances at both and 3 . Such a doubly resonant cavity greatly reduces the required power for efficient harmonic generation, by a factor of V /Q2, where V is the modal volume and Q is the lifetime, and can even exhibit 100% harmonic conversion effici...

A novel soft switching PWM converter for high frequency ACIDC andlor DCIAC power conversion is presented by using a new parallel resonant dc-link(PRDCL) and by adopting single phase soft switching(SPSS) technique. The new PRDCL provides variable link pulse position as well as variable link pulse ,width. which is quite different feature from the other resonant dc-links and thus the PWM capabilit...

Resonant power conversion at MHz frequencies is useful for miniaturization of power electronics, but requires resonators or inductors with high efficiency. Because litz wire is not effective above several MHz, an alternative winding structure for inductors is required for operation at these frequencies. In this paper, we present resonators with a multi-layer foil winding which can be constructe...

We propose coupled-cavity triply-resonant systems for degenerate-pump four-wave mixing (FWM) applications that support strong nonlinear interaction between distributed pump, signal and idler modes, and allow independent coupling of the pump mode and signal/idler modes to separate ports based on nonuniform supermode profile. We demonstrate seeded FWM with wavelength conversion efficiency of -54 ...

With the trend toward achieving high efficiency, power density and operating frequency in converters, a galvanic isolated circuit architecture is proposed this article for step-up applications with wide input-voltage range. This converter consists of current-fed resonant push-pull (PP) as dc transformer (dcX) dealing most efficiency an active clamp flyback (ACF) regulator within large conversio...
