In this paper a transformerless voltage source sine wave inverter is proposed. A previously developed tri-state boost converter is utilized for the stepping up operation. In this topology the dynamic response of the inverter is increased, by avoiding the right hand plane zero in the converter's small-signal control-to-output transfer function when operating in the continuous conduction mode. The reference voltage for the tristate boost converter is determined from the measured output voltage of the sine wave inverter and the calculated instantaneous value of the sine wave. The inverter with the tri-state boost converter and the inverter with a classical boost converter with voltage mode control and current mode control are compared for the dynamic response and efficiency. The analytical work of the design has been verified using a simulation. Furthermore, the boost converter is implemented in hardware to verify the boost inverter calculations. The current mode control and the tri-state logic hardware implementation are ongoing, and it is presented as future work. Finally, two user selectable modes are proposed for the inverter optimized for dynamic performance or efficiency.

“…The bandwidth as well as the transient response is limited by this RHP zero even with current-mode-control. Several literatures have been reported to overcome this RHP zero issue and try to enable a fast transient response [1][2][3][4]. Fixed-on-time control is one of them.…”

An integrated fixed frequency adaptive-on-time DC-DC converter with fast transient response is presented. To achieve fixed frequency, the slope information of the inductor current is employed to adjust the on-time and keep the switching frequency constant at 1MHz to within 10% variation across the whole input/output and loading ranges. An integrated boost converter with an input voltage of 1.8V to 2.4V and a regulated output voltage between 3.0V and 3.6V was implemented with a 0.35µm CMOS process. Simulation results show that the switching frequency variation has ~40% and ~30% improvement over the traditional input/output voltage controlled adaptive-ontime technique when the load current changes from 0.1A to 0.8A and the inductor ESR changes from 0Ω to 0.2Ω, respectively. The load transient response time is about 20µs when the load current changes from 200mA to 800mA.

“…The comprehensive analysis and verifications of the proposed control method will be presented here. The uniform controller exhibits the following properties: 1) it retains the advantages of boundary control with second-order switching surface for buck converter, such as fast dynamic response and well-defined control parameters; 2) the same controller is applicable for different type of converters with the input variables to the controller being modified accordingly, implying the feasibility to manufacture universal analogue controller ICs or provide universal digital solutions for different converters; 3) the switching surface for each converter is well-defined and does not need to modify the structure of power stage, like the ones (Viswanathan et al, 2005;Calvente et al, 2004;Krein, 2006).…”

Much effort has been made to the switching surface control of buck converter. However, it remains a fundamental challenge to apply the same concepts and associated control techniques to converters with non-minimum-phase characteristics. A nonlinear control method for all basic DC-DC converters (ie buck converter, boost converter, buck-boost converter, C ' uk converter and SEPIC) is proposed by deriving a uniform switching surface. It retains the advantages of boundary control for buck converter with second-order switching surface. For example, the converters can reach steady state in two switching actions after being subjected to large-signal disturbances. The derivations are general-oriented and can determine the circuit variables needed in the switching function. The same controller is universally applicable to different converters operating in both continuous conduction and discontinuous conduction modes. The potential applications lie in power conversions which require fast response to line/load changes, such as the point of load (POL) converters in the distributed power conversion system, power conditioning stage of the conversion system supplied by renewable energy sources, and so on. Design procedures and performance of the proposed control method applied on a 190 W 48/48 V buck-boost converter prototype will presented and compared with theoretical predictions.
