Lecture 8b 2 Control objectives in dc-dc converters + + _ V in V o I o • Regulate output voltage within +/-1% of reference, with varying input and dynamically changing loads • Control the output voltage to be at different voltages dynamically depending on load requirement • In battery charging applications, control the output current at an optimum value for fastest charging R L I in + V in • Control the input current precisely for variable loads and variable input voltages – current source applications • Control the input current such that power drawn from the input source is maximum - maximum power point tracking in photovoltaic systems Examples EEE 498/591 – Raja Ayyanar
