The inverter transforms DC power (battery, battery) into AC power (generally 220V50Hz sine or square wave).In popular terms, the inverter is a device that transforms DC (DC) into AC power (AC).It consists of inverter bridge, control logic and filter circuit.It is widely suitable for air conditioning, home theater, electric sand wheels, electric tools, sewing machines, DVDs, VCDs, computers, television, washing machines, hoods, refrigerators, video recorders, massage, fan, lighting, etc.
Inverter price
300 watts are about 750 yuan, 600 watts of about 1,300 yuan, and the price is lower.The inverter is a DCTOAC transformer. It is actually a process of voltage inverter with the converter.The converter is to transform the AC voltage of the power grid into a stable 12V DC output, and the inverter is to transform the 12V DC voltage output by ADAPTER into a high -frequency high -voltage AC power; both parts also use a more pulse wide pulse wide pulse width.Modification (PWM) technology.
The role of inverter
The inverter transforms DC power (battery, battery) into AC power (generally 220V50Hz sine or square wave).In popular terms, the inverter is a device that transforms DC (DC) into AC power (AC).It consists of inverter bridge, control logic and filter circuit.It is widely suitable for air conditioning, home theater, electric sand wheels, electric tools, sewing machines, DVDs, VCDs, computers, television, washing machines, hoods, refrigerators, video recorders, massage, fan, lighting, etc.To put it simply, the inverter is an electronic equipment that transforms low voltage (12 or 24 volts or 48 volts) to 220 volts.Because we usually turn the 220 volt flow electricity into DC electricity, and the role of the inverter is the opposite of this, so it is named.We are in an era of "mobile", mobile office, mobile communication, mobile leisure and entertainment.In the state of movement, people not only need low -voltage DC power supplied by batteries or batteries, but also requires our indispensable 220 volt communication electricity in the daily environment. The inverter can meet our needs.
Inverter circuit diagram
The functions and parameters of the TL494 inverter application circuit diagram TL494 are as follows: The first and 16th pin is the same phase input terminal of error amplifier A1 and A2.The maximum input voltage does not exceed VCC+0.3V.The second and 15th pin is the anti -phase input end of the error amplifier A1 and A2.The reference voltage detected by access error.The third foot is the output of the error amplifier A1 and A2.The input terminal of the integrated circuit is used to control the same phase input end of the PWM comparator. When the output voltage of any A1 and A2 rises, the output pulse of the PWM comparator is controlled.At the same time, the output end also leads to the end of the end to indirectly enters the RC frequency correction circuit and the direct negative feedback circuit with the 2nd and 15th pin.In addition, the 3 -pin voltage inverse ratio is wide to the output pulse, and this end function can also be used to achieve high level protection.
Reflers working principle
The inverter is a DCTOAC transformer. It is actually a process of voltage inverter with the converter.The converter is to transform the AC voltage of the power grid into a stable 12V DC output, and the inverter is to transform the 12V DC voltage output by ADAPTER into a high -frequency high -voltage AC power; both parts also use a more pulse wide pulse wide pulse width.Modification (PWM) technology.The core part is a PWM integrated controller, Adapter uses UC3842, and the inverter uses TL5001 chip.The working voltage range of TL5001 is 3.6 to 40V. There is an error amplifier inside, a regulator, an oscillator, a PWM generator controlled by a dead area, a low -voltage protection circuit and a short -circuit protection circuit.
What is the inverter
The inverter transforms DC power (battery, battery) into AC power (generally 220V50Hz sine or square wave).In popular terms, the inverter is a device that transforms DC (DC) into AC power (AC).The inverter is also known as the inverter power supply. It is a power conversion device that can convert 12V or 24V DC electricity into 240V, 50Hz AC power or other types of AC power.The AC power output can be used for all kinds of equipment, which meets the needs of users to communicate power supply to the maximum of mobile power supply places or users without electricity.
