Component selection and installation.
output voltage of the circuit can not afford to vibration or abnormal. Assembly between the two core layer thickness is about 0.03mm pad plastic film for core air gap.<br> Solar panels using four area of 6cm × 6cm silicon solar panels, its no-load output voltage of 4V, 40mA operating current when the output voltage is 3V. Since the efficiency of DC-DC converter with input voltage of the higher and higher, so four in series after the use of solar panels, when the circuit input voltage 12V. http://www.global-e-world.com/LCD-Monitor/ Readers can you buy solar panels to the specifications of the number and decided to use the connection method.<br> After installation, connected to solar panels, and placed the sun, no-load circuit output voltage of about 4.2V, when the no-load output voltage higher than 4.2V and can be properly reduced the resistance R5, the other hand increase the R5 of resistance. Circuit current with the intensity of the sunlight, normal is about 40mA, then the charge current is about 85mA.<br> Close of the VT1, http://www.global-e-world.com/Touch-Screen-LCD-Monitor/ DC power supply input voltage and the negative Nb 3 induced voltage has been 4 positive R1, R3 to C2 reverse charge, and gradually raise the base potential of VT1, to re-turn, turn again to reach saturation state, repeat the circuit oscillation going on this way. R5, R6, VD2, VT2 circuit composed of voltage limiter to protect the battery charge is not over here to 3.6V mobile phone battery, for example, limit its charging voltage 4.2V. In the process of charging the battery, the battery voltage gradually increased, when the charging voltage is greater than 4.2V, the by R5, R6 partial pressure began after the regulator diode VD2 conduction to conduction VT2, VT2 diversion effect of reduced VT1 base current, thus reducing the VT1 of the collector current Ic, to limit the output voltage. Then the circuit to stop charging the battery of high current, with a small current to the battery voltage is maintained at 4.2V.
