If the lines which connect the output terminal of DC-DC converter and the load are long the voltage actually across load will be changed largely to produce the voltage drops by the impedances of the lines. Then, the terminal which senses the voltage across load is prepared apart from the output terminal of DC-DC converter, and it leads to the load, and the voltage across load is adjusted so that it...

Robust DC-DC converter which can cover extensive load changes and also input voltage changes with one controller is needed. Then the demand to suppressing output voltage change becomes still severer. We proposed an aproximate 2DOF digital controller which realizes the startup response and dynamic load response independently. The controller makes the control bandwidth wider, and at the same time makes...
A new concept of maximum power point tracking control method for Thermoelectric Power Generator (TEG) systems has been developed. The virtual load conductance of the load is feedback controlled to maintain the same value of the internal conductance of the thermoelectric (TE) array using DC-DC converter. The prototype Maximum Power Point Tracker (MPPT) circuit, which is composed of buck-boost DC-DC...
In many applications of DC-DC converters, loads cannot be specified in advance, i.e., their amplitudes are suddenly changed from the zero to the maximum rating. Generally, design conditions are changed for each load and then each controller is re-designed. Then, a so-called robust DC-DC converter which can cover such extensive load changes and also input voltage changes with one controller is needed...
