Low Frequency Inverters with Built-in Chargers

Click: 406    Date: 08/01/2023 5::27::06 PM

Low frequency inverters are a type of power inverters that operate at low frequencies, typically around 60 Hz. They are distinguished from high frequency inverters by the size of their transformers and the switching speed of their transistors.These inverters are designed to convert DC power (Direct Current) into AC power (Alternating Current), which is used to run household items and electrical appliances. This makes them an essential component for anyone without access to a mains power source, as they can provide a plentiful amount of electricity.Advantages of Low Frequency InvertersLow frequency inverters have several advantages over their high frequency counterparts. They are designed to handle higher power spikes for longer periods, making them more robust and reliable. This capability is particularly important for devices like power tools, pumps, and appliances with electric motors that require high starting power. Low-frequency inverters can operate at peak power levels up to 300% of their nominal power level for several seconds, whereas high-frequency inverters can only operate at 200% power level for a fraction of a second.Another advantage is their reliability. Low-frequency inverters operate using powerful transformers, which are more reliable and sturdy than the high-frequency inverter’s MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors), which use electronic switching and are more prone to damage, particularly at high power levels.Built-in Charger and Other FeaturesIn addition to their robustness and reliability, low-frequency inverters come with a wide range of technical features and capabilities, including a built-in battery charger. This feature allows the inverter to charge a battery from an AC power source, such as a generator or shore power at an RV park, truck stop, or home.Other features of low-frequency inverters include UPS (Uninterruptible Power Supply) functions, bypass mode with no battery connected, power saving mode, and various charge settings for different battery types and charging voltages.Applications of Low Frequency InvertersLow frequency inverters are designed for large off-grid power systems and are more suitably equipped for powering heavy appliances. They are typically used in power levels within the thousands, such as 2000W-3000W and above. They are ideal for powering various kitchen appliances, such as refrigerators, microwaves, dishwashers, ovens, and devices with electric motors like power tools, washing machines, vacuum cleaners, and air conditioners.Despite their larger size and weight compared to high-frequency inverters, low-frequency inverters are a great investment for anyone with a lot of powerful electrical appliances in places with limited or no access to standard electricity. They can provide a reliable backup power solution and even completely replace conventional electricity with the same quality power supply.

Frequency converter

Frequency ConverterA frequency converter, also known as a frequency changer, is a device that converts the frequency of an alternating current (AC) from one value to another. Besides changing the frequency, these devices may also alter the voltage, but this can be considered incidental to their primary function. Voltage conversion of AC is much simpler to achieve than frequency conversion.Types of Frequency ConvertersFrequency converters can be broadly classified into static, rotating, and combined types.Static Frequency Converters: These can be further subdivided into electromagnetic and rectifier types. Electromagnetic frequency converters are based on changing the shape of a sinusoidal alternating voltage using magnetic nonlinear elements, such as chokes and transformers with saturable cores. They are often used as frequency dividers and multipliers . Rectifier-type converters often employ transistors and thyristors as rectifiers, and are primarily used in radio-engineering equipment. Their power rating can be as high as 2 to 3 kilovolt-amperes (kVA).Rotating Frequency Converters: These converters can be built either as two machines or as one machine. The two-machine type usually combines an electric driving motor and a generator of alternating or direct current. Their efficiency can reach 85 percent, and their power ratings range from 30 to 800 kVA.Applications of Frequency ConvertersFrequency converters find usage in various applications, including:Power Grids: They are used for converting bulk AC power from one frequency to another when two adjacent power grids operate at different utility frequencies.Variable-Frequency Drives: A variable-frequency drive (VFD) is a type of frequency changer used for speed control of AC motors. The speed of a synchronous AC motor is dependent on the frequency of the AC power supply. Therefore, changing frequency allows the motor speed to be varied.Aerospace and Airlines Industries: Often airplanes use 400 Hz power, so a 50 Hz or 60 Hz to 400 Hz frequency converter is needed for use in the ground power unit used to power the airplane while it is on the ground.Renewable Energy Systems: In renewable energy systems, frequency converters are an essential component of doubly fed induction generators (DFIGs) as used in modern multi-megawatt class wind turbines.Frequency Converter TechnologyThere are two basic types of Frequency Converters: Rotary Frequency Converters and Solid State (Static) Frequency Converters. Rotary Frequency Converters use electrical energy to drive a motor. On the other hand, Solid-state frequency converters take the incoming AC and convert it to direct current (DC).A Rotary Frequency Converter is manufactured with the use of a Motor Generator and a Solid State (Static) Frequency Converter is manufactured with the use of semiconductors and power stages. The Rotary machine is brute force as opposed to the Static machine.In conclusion, frequency converters are crucial devices in various industries due to their ability to convert the frequency of an alternating current. They are particularly important in applications that require the control of motor speed, synchronization of different power grids, and in the operation of specific equipment in the aerospace industry.
