Brief introduction of circuit diagram of the inverter and principle

The inverter is a device that converts direct current (DC) from a battery or storage battery into alternating current (AC), typically at 220 volts and 50 Hz, producing either sine waves or rectangular waves. It serves as a common emergency power supply, allowing for the conversion of DC from batteries to AC for various applications. In remote areas or during power outages, inverters are essential. A common type is the Uninterruptible Power Supply (UPS), which is utilized in computer labs to prevent data loss during unexpected power failures by converting stored battery DC into AC. Inverters are known for their reliability and stability, and they can also be used in conjunction with generators to improve fuel efficiency and reduce noise. They are particularly important in renewable energy applications, such as wind and solar energy. Small-scale inverters can provide AC power for devices in outdoor settings. This text will present two simpler inverter schematic diagrams designed for 150W output, operating at approximately 300 Hz with a rectangular waveform. These inverters can be used during power outages to power household appliances like electronic ballasts and switching power supplies. The design converts 12V DC into 220V AC, using a circuit with components such as BG2, BG3, BG1, BG6, BG7, and a resonator powered by BG5 and a stabilized voltage supply. The output frequency remains stable, with a transformer capable of handling the conversion from 12V to standard city power. The circuit is powered by a 12V battery, and an operational amplifier module is used for voltage doubling. The operational amplifiers generate reference signals and serve various roles in the inverter's operation, including as a hysteresis comparator and part of a switching power supply.

The inverter circuit described operates on the principle of converting 12V DC to 220V AC, which is achieved through a series of operational amplifiers and switching components. The primary components include BG1, BG2, BG3, BG5, and gas switching tubes. The circuit begins with a voltage doubling stage, where an operational amplifier, such as ICL7660 or MAX1044, generates a 50 Hz sine wave as a reference signal. This reference signal is critical for the operation of the inverter, as it provides the necessary timing for the switching elements.

The inverter employs a multivibrator configuration using BG2 and BG3, which generates a square wave output. This output drives BG1, which in turn controls the operation of the gas switching tubes (BG6 and BG7). The switching frequency is determined by the feedback from the operational amplifiers, specifically operational amplifiers 3 and 4, which function as hysteresis comparators. These comparators ensure that the switching action of the gas tubes occurs alternately, allowing for the conversion of DC to AC.

The output stage of the inverter utilizes a transformer capable of stepping up the voltage from 12V to 220V AC. The transformer is designed to handle the output waveform, which is primarily rectangular due to the nature of the switching action. This design choice balances the need for simplicity in construction and the requirement for a compact form factor.

In practical applications, the inverter circuit can be used to power various household devices during a power outage, including lighting systems and electronic appliances. The choice of components and the overall design emphasize reliability, ease of assembly, and effective performance in converting DC to AC power. The inverter's ability to operate efficiently with renewable energy sources further enhances its appeal in modern applications, where sustainability and energy independence are increasingly prioritized.The inverter is kinds of direct currents can battery, storage battery Change into alternating current generally 220 volts of 50HZ sine waves or rectangular waves Device. Our common emergency power supply, 220V exchange to generally all invert the direct current bottle. Come briefly and say, the inverter is that one kind turns direct current into e xchanging the electric device. No matter in the remote mountain village, either open-air need or the black out meets an urgent need, the inverter is a very good choice. The more common one is UPS power which will be used in computer lab, in the unexpected black out, UPS can invert and exchange and is used as computer the direct current of Reed of storage battery, thus prevent the data caused by unexpected deenergization from losing the question.

Can the at a stretch offer the power, have sure safe reliability, stability. The inverter can also be with the corollary use of the generator, Yes the economy of fuel, reduction noise effectively, in the fields of wind energy, solar energy, the inverter is more essential. Small-scale inverter usable car, steamer, portable power supply equipment offer the AC supply outdoors.

This text will introduce two kinds of simpler inverter schematic diagrams. This kind of design, the material is apt to fetch, output power 150W, this circuit designs frequency as about 300HZ, the purpose is narrowing and reversing the volume, weight, output waveform rectangular wave of the voltage transformer.

This inverter is comparatively apt to make, can go against 12V direct-flow mains voltage to turn into the voltage of 220V city power, the multivibrator of the circuit composed of BG2 and BG3 is pushed, and then drive through BG1 and BG2, to control BG6 and BG7 work. Resonator supply power by BG5 and the intersection of DW and stabilized voltage supply of group, so can make, output frequency comparison to be steady among them.

While producing, voltage transformer available to have daily pairs of city power voltage transformer that 12V exports. Depending upon need, are chosen the appropriate 12V battery capacity. 12V is battery-driven that this circuit takes.
