Converters step-up

The step-up converters (also known as a boost converters) is an power electronic converter, which is designed to increase the direct voltage (DC) from the source, receiving an appropriately increased DC voltage for the receivers at the output. The main purpose of devices such as DC-DC voltage converters, step-up and step-down converters is to power various types of electronics.

The construction of switched-mode power supplies is based on such converters. The working elements of the step-up converter include switching semiconductor elements, capacitors and / or energy storage coils and anti-interference filters. For step-up products, the lower input voltage can be changed to a higher output voltage by adjusting the 'v-adj' potentiometer.

In this category, we present you the best step-up converters that can be confidently used for various electronic, automatic, robotic and many other projects. Due to the fact that the correct operation and implementation of this device into the project requires knowledge, it is recommended to read the manual. Before that, check the product details on its product card. We invite you to place orders!

How does a step-up converter work? The principle of operation

The step-up converters offered by the Botland store are in most cases equipped with an output voltage regulation system. Step-up converters are very widely used thanks to this feature. There are, for example, their use in projects requiring increased supply voltages of non-standard values.

Understanding how a step-up converter works requires knowledge of basic physical and electrical engineering. A transistor key and a diode are used in the step-up converter circuit. When the keying transistor closes the circuit through the coil and the power source, the diode in the switching circuit goes into the reverse state. This is because the voltage at its cathode is higher than at its anode.

The basic principle of operation in step-up converters is the operation of the coil consisting in maintaining the continuity of the current due to changes in the magnetic field. Importantly - the voltage at the output is always higher than at the input. As the transistor conducts, the current through the inductor creates magnetic field energy. When the switching transistor of the device ceases to conduct, the current flowing from the source through the coil disappears. According to Faraday's law of induction, the previously accumulated energy of the magnetic field is converted into a voltage summed up with the voltage of the source, which supplies the receiver via a diode and charges the voltage-holding capacitor connected to it in parallel. The keying transistor is driven by a square wave with variable duty cycle (PWM). By default, it is assumed that the greater the duty cycle, the higher the voltage at the output of the step-up converter.

Highest quality adjustable step-up converters 

In this category, we present various types of converters, made by well-known and recommended manufacturers. An example is the group of U3V70X step-up converters from Polou. These are high-performance converters with synchronously switching regulators that require a minimum voltage of 2.9V. Immediately after switching on, the regulator limits the input current to 10.0A. The converters are equipped with overload, short-circuit and undervoltage protection, and the recommended maximum continuous output current is 6.0A. The output current is proportional to the ratio of the input voltage to the output voltage, which means that the output current decreases as the output voltage from the inverter increases.

Products with such specifications as the above-mentioned Polou converters also have built-in protection against voltage with reverse polarity, thus protecting the receivers. Built-in low-energy transition function prevents unnecessary energy waste. Converters of the U3V70X group are available in a version with a rigid output voltage in variants from 5.0V to 15.0V and in a version with precisely regulated output voltage in variants from 4.5V to 20.0V, using a 12-turn potentiometer.

Step-up converters are the advanced devices 

Converters offered by the Botland store are in most cases equipped with an output voltage regulation system. Thanks to this solution, they can be used in projects requiring increased supply voltages with non-standard values.

Step-up converters are advanced products. They are very useful for many projects, but before choosing them, you should read the specification of a specific product and how it works. Incorrect connection of power polarity will damage the inverter. You should be able to check the output voltage and adjust the correct parameters with a potentiometer. Step-up converters are a device designed for experienced DIY enthusiasts. In this case, at least basic knowledge of electronics and soldering skills will be useful. When shopping in Botland, you can be sure of getting the highest quality, original electronic components.
