I am developing a boost converter that boosts 12V input to 48V. My load is 100 ohms. I have done a simulation on MATLAB Simulink and by connecting a voltmeter and ammeter on the load, I observed that it draws 45.73 (output voltage) x 0.457 (output current) = 20.89 Watts power. I understand that the power dissipation across the 100 ohms load resistance is now 20.89 Watts. I connected an ammeter on the input side and noticed that it draws 2.15 Amperes from the 12 Volt source. Does this mean that my circuit needs (2.15 x 12 =25.8) watts to function? Can a 12V 1.2 Ah lead acid rechargeable battery provide this? Plus I need the battery to be charged via a solar panel. Should I buy a 30 Watt panel as its the closest one available to the desired 25.8 Watts?
