“…This function behaves as a second-order function for high frequencies: (4) This means that the buck converter with input filter cannot be used for this application. The second-order behavior of this function will result in an unstable operation of the PWM conductance control loop (see next section).…”

“…The proposed control technique is called "two-domains" because it is given by the combination of a linear control, called conductance control, well described in [5] and widely used in space, and a non linear part (called NL-control in the present paper), which is based on the detection of the output voltage variation and comparison of this variation with a pre-determined threshold. During a load transient, in case the output voltage crosses a threshold, the NL-control is activated and forces maximum or minimum inductor current.…”

In the design of a power converter, the maximum output voltage transient under load change is one of the main drivers. The ECSS-E-ST-20C imposes specific requirements on the power quality of a regulated bus, which result most of the time in the use of a large capacitor bank to cope with the linear loop dynamics. Moreover, this sometimes results in slow dynamic response.In this paper a combined linear and non-linear control applied to a buck converter is proposed. This control technique enhances the transient performance with a faster recovery time and allows smaller output filter capacitors to be used. The proposed control is a combination of a linear control based on a conductance control principle, and a non-linear control, which intervenes only during transients. The latter is based on the detection of the output voltage variation and on the immediate application of maximum or minimum inductor current, as consequence of voltage undershoot or overshoot. Once the controlled output voltage is within the allowed range, the linear control takes back the voltage regulation control.The buck converter is chosen as a reference topology since most of the current solar array regulators (SARs) use a buck or super buck topology. Most Battery Discharge Regulators (BDRs) are also based on buckderived topologies.This concept can find application in the three-domain regulated bus control.

The present paper shows the preliminary results of a project that looks for a high power, high efficiency bidirectional step-up converter which could be used as a battery discharge/charge regulator. High efficiency and low mass are the main goals, no galvanic isolation is required and MTBF should be as large as possible. Taking into account all these parameters our proposed solution has been a new topology based on a Boost converter with output filter and that couples input and output inductor. The use of a bidirectional converter reduces the mass of the overall charge/discharge subsystem and lowers cost and component count. Stability has been studied theoretically and verified experimentally.
