By has C1 value 10 microfarad power smoothing control. That is the voltage at the combined pass diode D1 to supply to the output. Serial-in phase with occurred voltage occurred the output is equal to +5 volts. L1 is connected to the terminals voltage of the input voltage is negative. That is, L1 is cut out of the ground, the magnetic field of the inductor L1 and the voltage collapse occurred first. Makes the transistor T2 conduct bias of T1 is to pull off. When the current of the coil will increase the voltage across R1 have value about 0.8-1.2 volts. When T1 conduct causes the linearly current with coil L1, the current flow through the coil is the same as the collector current or the emitter current of T1. And its bottom terminals is a negative voltage. Resulting voltage drop across L1 equal to the power supply voltage by the voltage of +5 volts L1 is connected to a positive voltage. Making T1 conduct while L1 is connected to ground (or potentially negative light). The results of the transistor T3 has a bias, making it rise to Conduction provide current from emitter out to collector sent directly to the bias of base of transistor Q1 Makes T1 into conduction state to another. Through R3 to reach the potential removal of the input voltage.

Because it is the only one with a full bias current flows through R4 +5 volts to pin emitter to base. When the power supply to a transistor circuit T3 to the conduction system. Figure 2 the complete circuit of the boost converter 5V to 12V has effective in the range of 77%
