DC to DC converter circuit size and quite a lot of small passive components used PWM control TL494 SMD type
Matchbox output coil in comparison with the size of the image of the PC power supply-12v -5 volts output the same as in the core of filter coil (the coil can not be found alternatives to the song)
# Input Voltage – 12V to 15V DC
# Output voltage – 15V .. 25V
# Maximum Efficiency – 88%
# Maximum Power Output – (Uwe 5.5 x). 66W 12V to 14V, Pmax = 77W
# Output Current Continuous – i19v 12-14V, Imax = 3,5-4A
# Operating Frequency – 200kHz. 100kHz
DC to DC Converter Circuit
Boost converter, a two-phase system with very low noise and input current ripple and output voltage. It is a small inverter with a very high capacity, dimensions: 80mm x 53mm x 16mm, giving it more than 1W/cm of the output power of 70W. By using two reactors that operate out of phase, the current one is about half that of a conventional inverter and is charged alternately, which eliminates the large spikes of current drawn from the battery. The inverter has one drawback, the maximum output voltage can not exceed (Uwy.max = Uwe x 1.8 – 2), which can be done with 12V max 19,6 V.
