“…Thus it can be seen that the overshoot and settling time are smaller when the current control and the voltage control are used. Besides the evidence through simulation results more accurate when applied controllers for current and voltage, this type of controller becomes interesting in controlling associated converters in parallel, as shown in [17] or still in control of DC motors , [18].…”

In this paper, a new non-insulated DC-DC converter called Double Quadratic Buck Converter is proposed. This new converter has the advantages of high gain ratio near half range of duty cycle compared to the conventional Buck Converter. The stress voltage over the switches is reduced to half of the value compared to the conventional Quadratic Buck Converter. The topological symmetry simplifies the theoretical analysis of the converter. A complete theoretical analysis is made. The converter operation stages with the respective waveforms are explained. Static gain, critical inductance and boundary conduction mode are equated in order to obtain the external behavior curve of the converter. Besides the static model will be presented in this paper the dynamic model of the converter and the control of input current and of output voltage.Words -Keys -Buck Converter, Quadratic Buck Converter, Double Quadratic Buck Converter.

“…This opens the option of using established and widely known frequency domain robust control methods such as loop-shaping [15] or multivariable state-feedback control [16]. The small signal paradigm requires the converter to be switched with a constant period, such as by fixed-period PWM control (which is thus a time-constrained control).…”

The concept of large signal controllability for switched electrical networks is reviewed for dc-dc converters. Small signal models and controllers are limited by assumptions of fixed operating point. Hybrid system representations allow use of geometric control methods including sliding mode and boundary based switching controls.The comparison of geometric control response with small signal response shows a fundamental difference: only geometric methods are capable of deadbeat (finite time duration) recovery to steady-state after a transient disturbance. However, these deadbeat geometric laws are only known for second order systems. The possibility of deadbeat control for higher order dc-dc converter systems is examined. Keywords-dc-dc converter, geometric control, state-plane analysis, switched sytem, hybrid system, null audio susceptibility, deadbeat response, small signal model, large signal model.I. 0-7803-9033
