What is an inverter (Inverter)Sometimes called "V/F Control" inverter (Inverter) also have a name called.• VSD : Variable Speed Drives• VVVF : Variable Voltage Variable Frequency• VC : Vector ControlThe principle function of the inverterInverter (Inverter) to convert AC power from the power supply voltages, and generally a constant frequency to a direct current (DC) power by con Inverter circuit (Circuit Converter), DC power is then converted to AC power which can resize, volts and frequency by circuit inverter (Inverter Circuit) circuit, the two will be the primary circuit that converts energy of waves and inverters.In General, the power supply is AC wave science. But the output of the Inverter is different from science of waves. There is also a chutwongchon control (Control Circuit) controls the operation of the circuit and inverter inverter icons to suit the properties of the 3-phase Induction motor.The internal structure of the Inverter1. the continental series inverter (Converter Circuit). The switch from AC power AC power supply (50 Hz). into the fire (DC Voltage)2. series inverter (Inverter Circuit). Direct voltage (DC Voltage), a power switch (AC Voltage) that can change the voltage and frequency.3. chutwongchon control (Control Circuit). Control of the inverter and inverter series icon.For example, the operation of the inverter (Inverter) found in the present, including the use of electrical equipment to power back up or UPS (Uninterruptible Power Supply) to solve the problem of excess light, fire, power outage and wave interference. Helps prevent damage to electrical power reserved by be stored in batteries.Example If a power level. Your system will switch from battery power to come immediately. An electric current, which is then made into the inverter which changes DC into AC power at a constant frequency and correct. AC power inverter, the output will be entered into the General electric engines that power the AC output will be conducting the feedback compared to the reference frequency one and the result of the comparison to the birth control of the frequency inverters to provide AC power at a constant frequency and correct. According to AC appliances.Inverter (Inverter) is used in various appliances such as air conditioners, refrigerators, televisions and servo motor control (Servo Motor), due to the need to reduce losses are high, especially when the job starts and losing in the built-in coils and iron cores (for machine tool design and motor), which is the job loss or electricity is:When the appliance starts to flow I (Start) start higher. While walking up to 4-6 times the normal, such as air conditioning motor size 220 V, 1 A.Pnormal = 220V 1A = 220WWhile starting the motor or transformer will retrieve the stream to create a magnetic field with at least 4 times as normal.Pstart = 220V (4 1A) = 880WSystem was originally non-inverter will be charged very high levels of unstable line voltage (Stable) as well as cause voltage spike while stopped, where these things will cause damage to electrical equipment or SAP the life.Sample problems and solutions by bringing the inverter (Inverter).The operation of the air conditioning. The system will run consecutively, dap khrua. problems with other electrical equipment also has a high power to remove inverter systems come correct. Make the air motor is working with non-fire. Like in the original system, which proved that "the continuous working motor helps save energy and electricity than to stop and start a new journey of at least 1 or more", that is the principle of work. Is as follows: While visiting the State. Series inverter will order the motor to work more (faster) by increasing the frequency or Duty Cycle and as modified by the constant temperature system or standard inverter to reduce the function of the motor down (slow), but it does not stop the operation of the motor, which reduces the capacity used.Inverter is used in systems such as.1. use a power backup supply or a Stand called Uninterruptible Power Supplies by power (UPS) to substitute in case of AC power failure occurs, the main.2. is used to control the speed of AC motor by using the principle of frequency control of AC voltage. In order to provide a constant torque (Torque) every speed changes.3. use the voltage from transmission high voltage DC, a type of AC power to the services provided to users.4. furnace to smelt iron systems that use the principle of induction to heat (Induction heating), which AC applied voltage, high frequency work.
