“…Nevertheless, despite this advantage, the single switch (S) involves high stress both in current and voltage restricting the delivered power value to the load . Furthermore, due to the DBD being a time varying load, the class E amplifier is detuned further, which increases the voltage and current stress in the switch …”

Summary In this paper, the analysis, design, and implementation of a power supply based on a multi‐stage‐shunt class E amplifier applied to ozone generation are presented. The proposed topology operates with pulsating waveforms and allows unidirectional energy flow from the power supply to the load with no energy return. Furthermore, due to the multi‐stage operation, it presents a lower stress in the switches compared with other similar topologies. To validate the proposed topology, a prototype was designed to feed a set of ozone generating cells in a power range of 0 to 500 W. This prototype provides an efficiency of 95% with an ozone production of 10.5 g/h and efficacy of 22.89 g/kWh. The proposed power supply is an alternative to feed any other type of dielectric barrier discharge load while keeping the efficiency of the power supply above 90%.

“…27 Furthermore, due to the DBD being a time varying load, the class E amplifier is detuned further, which increases the voltage and current stress in the switch. 28,29 The use of the DBD to generate ozone requires a high-level voltage (>3 kV). This and the previously mentioned condition imply a very high voltage in the switch.…”

“…Such a rectifier system exhibits poor dynamic response against input voltage and load disturbances. The output voltage is unsteady, when there is pulsed loading [9] and/or the input voltage contains dips or swells due to frequent additions or rejections of bulk loads connected to the supply. As a result, the components of the rectifier and its downstream converter experience increased voltage and current stresses.…”

This paper presents a generalized feedforward control scheme for a single-phase boost rectifier, operating with indirect current control, to improve the dynamic response of its output voltage against line and load disturbances, as well as for changes in the reference voltage. Digital implementation of the control method is discussed. A small-signal model of the converter system is presented. The stability of the current loop at light loads is studied. A method is presented to estimate the input voltage and the load current without having to actually measure these quantities for the purpose of feedforward control. Simulation and experimental results are presented.
