Non-thermal plasma technology systems often require high voltage, AC power supplies. Paper discusses a novel power electronic converter topology enabling high voltage, high frequency operation with resonant, quasi-phase-mode output voltage control. System topology, simulation results and experimental properties are presented and discussed.
In this work a two-stage boost converter circuit is investigated. Relations for the dimensioning of the converter elements are given and a realistic converter model is derived and presented using state-space description. The transfer functions for the output voltage depending on the duty ratio and the input voltage are calculated and topologies of possible voltage control systems are suggested. The...
Stability is an important design consideration in power electronics systems. To this end, it is often of interest to predict the region of attraction (ROA) associated with a stable equilibrium point. In the case of the presence of constraints that need to be satisfied, one is faced with the problem of estimating a restricted ROA (RROA). Recently practical methods for estimating RROAs have been proposed...
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
