When to Use a Boost Converter in Power Systems?

In Case Voltage Input Is Below Load Demand

Boost converters are commonly used in cases wherein power input voltage from the power source is below the input voltage requirement from the load. AA battery powered small electronic devices are a good example. These devices typically run on 1.5V from batteries. In cases where the device requires 5V to run its circuits, a boost converter allows step-up of that 1.5V to a 5V. This ensures stable device operation, without the need to switch the power source.

For Renewable Energy Systems

As an example, solar panels and wind turbines are a good example of renewable energy systems which have the capability of providing variable voltages depending on external conditions: solar panels operate at lower voltages in cloudy weather. A boost converter serves an important purpose in this regard: it takes low voltage from the panels and converts it to the required value needed by batteries or grid-tie inverters. This ensures optimal use of low energy in low light or weak wind conditions.

In Battery Operated Devices  

Devices such as portable medical equipment, robots, or outdoor sensors powered by batteries require constant power to function optimally. Battery output voltage diminishes as the batteries discharge. A boost converter compensates for voltage that is lost by stepping the voltage up to the required level for the device. This enhances battery lifespan, reduces the need for frequent replacements, and enables the device to function for longer durations between charges.  

In Industrial Automation  

In industrial machinery and automation equipment, and even manufacturing robotics, there are usually components that operate on different voltage levels. For example, a conveyor belt system has control circuits that operate at a 24V, while its main power for the motors is 12V. A boost converter is able to fill the gap between the two levels by transforming the 12V to 24V for the control circuits. This even improves the simplicity of system design, as different components can be assembled together without the need for several special power supplies.

Key Considerations When Choosing a Boost Converter

When selecting a boost converter, prioritizing efficiency comes first. For systems relying on batteries or renewable energy, energy loss is vital, making high-efficiency models a necessity. Other factors like reliability also matter, especially in harsh environments like industrial and marine settings. Tough or waterproof boost converters with IP65 rating or similar rugged design are able to endure harsher conditions. Ensuring compatibility with voltage range and application specific-load current helps patent possible performance issues. Carefully checking your provider’s model range is also important. For more than 500 models, providers like these can cater to all sorts of small and big electronics.
