Σύνοψη

This project has as main parts a push-pull transformercoupled
circuit and a flyback converter circuit. The idea is
to use as input a low voltage battery. By the help of a
sensitive electronic switch (for the control part) one
becomes aware of the severe problems, disturbances through
an inductor to charge a capacitor. This sensitive electronic
switch was chosen to be the SG3S24. It is an industrial
standard.
The SG3S24 regulating pulse width modulator contains
all of the control circuitry necessary to implement
switching regulators of either polarity, transformer coupled
DC to DC converters, transformerless polarity converters and
voltage doublers as well as other power control application.
This device includes a SV voltage regulator capable of
supplying up to SOmA to external circuitry, a control
amplifier, an oscillator, a pulse width modulator a phase
splitting flip-flop, dual alternating output switch
transistors and current limiting and shutdown circuitry ••
The features of this ic are:
I. Complete PWM power control circuitry.
II. Frequency adjust to greater than 100 KHz.
III. 2.% frequency stability with temperature.
IV. Total quiescent current less than 10mA.
v. Dual alternating output switches for both push-pull or
single ended applications.
VI. A current limit amplifier provides external component
protection.
VII. SV, SOmA linear regulator output available to user.
The Capacitor (4.7~F, 2S0V) Figure 1.1 acts as a high
voltage source giving an input to an autotranformer. Hence,
will get an extremely high voltage from autotransformers
output.
