Boost Converter Circuit

The circuit boosts the voltage from the supply hence named as boost converter.

Boost converter circuit.

The input voltage is supplied through a 3 7 v battery which has its anode connected to the pin 6 of the regulator ic and cathode connected to the common ground. A capacitor inductor or the two in combination. As the name suggests it takes an input voltage and boosts or increases it. These are the same levels that i recommend for switching from a non synchronous buck to a synchronous.

The rest of the components are the same as those used in the buck converter illustrated in fig. A boost converter circuit is a design intended for stepping up or boosting a small input voltage levels to a desired higher output voltage level hence the name boost converter. So for example you may be able to convert a 5v dc voltage into 30v. 3 2 1 illustrates the basic circuit of a boost converter.

A boost converter is one of the simplest types of switch mode converter. A dc to dc converter works on the principle of an inductor primarily and a capacitor. Although a boost converter circuit may involve many complex stages and calculations here we will see how the same could be built using minimum number of components. A dc to dc boost converter circuit is a circuit that can convert a dc voltage into a larger dc voltage.

A boost converter step up converter is a dc to dc power converter that steps up voltage while stepping down current from its input supply to its output load. All it consists of is an inductor a semiconductor switch a diode and a capacitor. It is a class of switched mode power supply smps containing at least two semiconductors a diode and a transistor and at least one energy storage element. For circuits with a high output current generally starting above three amps and especially five amps or more replacing the output diode with a mosfed makes a lot of sense both for efficiency and for heating.

The boost converter however does not involve the tedious method of converting dc to ac then stepping up the voltage and then converting the stepped ac voltage to dc. It is equivalent to a flyback converter using a single inductor instead of a transformer. When fed dc power the inductor acts as a energy storage device for current. In this project the boost converter circuit is built using the 34063a dc to dc converter ic.

There are many ways to converter a lower dc voltage to a higher one. The buck boost converter is a type of dc to dc converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. A capacitor cin is connected at the pin 6 for removing ripples from the input signal.
