Abstract: This paper presents a novel design procedure for Class E amplifiers without using waveform equations. By the proposed design procedure, Class E amplifiers can be designed regardless of the Q factor of resonant circuit, existence of the switch on resistor, and so on. The proposed design procedure requires only circuit equations and design specifications. All design procedures reported until now require deriving waveform equations which requires a lot of work. The benefits of the proposed design procedure is that it is to deriving waveform equations is no longer necessary. When the circuit equations are obtained, the other procedures for computation of design values are carried out with aid of computer. Therefore, we can design Class E amplifier more easily than the conventional design procedure. The authors design Class E amplifiers by using the proposed design procedures and carry out the circuit experiments, and find that the experimental results agree with calculation results, and show the validity of the proposed design procedure.

TL;DR: In this paper, a cost-effective piezoelectric transformer based ballast circuit was designed to drive a linear fluorescent lamp without dependence on any magnetic devices, which can work in a ZVS (zero-voltage switching) condition.
Abstract: This paper presents a cost-effective piezoelectric transformer based ballast circuit that is designed to drive a linear fluorescent lamp without dependence on any magnetic devices. This innovative circuit uses a radial vibration mode piezoelectric transformer or Transoner(R) to replace the inductor and the capacitors of the resonant tank portion in conventional electronic ballast circuits in order to effectively reduce the component number and cost. By fully utilizing the characteristics of the radial vibration mode piezoelectric transformer, the switches of the ballast circuit can work in a ZVS (zero-voltage switching) condition thus significantly reducing the turn-on switching losses when compared to a hard-switching topology. In addition, the inherent input capacitance of the radial vibration mode piezoelectric transformer enhances circuit operation by serving as a turn-off snubber for the half-bridge switches. This decreases turn-off voltage spiking thus reducing the turn-off losses for the half-bridge switches of the proposed circuit. Through these innovative circuit techniques, the proposed circuit provided 32-watts of power at commendable efficiency of around 90% when utilizing a standard 110-volt 60-Hz line as the power source and a 4-foot 40-watt linear fluorescent lamp as a load.

TL;DR: The balancing booster improves the balancing process in these converters, making it independent of the load, and can also reduce oscillations that arise in the converters in transient states.
Abstract: This paper presents investigations of voltage-sharing stabilization with the use of passive RLC circuit in switch-mode flying capacitor DC-DC converters. Practical and simulation results and also a mathematical analysis of the balancing process in boost and buck-boost converters are presented. Analyzed converters use additional capacitors (flying capacitors), charged to proper value, for decreasing the voltage on switches and increasing the inductor-current frequency. Such advantages are achieved under proper voltage sharing on the flying capacitors. The voltages are stabilized in a natural way by the load current and with the use of external RLC circuit to force the current that flows through the converters' capacitors under unbalance state. This paper focuses on the analysis of the balancing phenomenon with the use of the external RLC circuit in these topologies. The balancing booster improves the balancing process in these converters, making it independent of the load. It can also reduce oscillations that arise in the converters in transient states.
