Inverter (Inverter) is
sometimes referred to as "V / F Control" Inverter (Inverter) also have known several
• VSD: Variable Speed Drives
• VVVF: Variable Voltage Variable Frequency
• VC: Vector. Control
Principle of inverter
Inverter (Inverter) converts AC power (AC) from the power supply voltage and frequency are generally fixed. A light current (DC) circuit converters (Converter Circuit) and DC power is converted to AC power with adjustable voltage and frequency by the inverter (Inverter Circuit) circuit, these two will be. The main circuit that converts the waveform. And through the power of the inverter
typical AC power supply with a sine wave. But the Inverter output waveform is different from the sine. There was also a control circuit (Control Circuit) controls the operation of the converter circuit and the inverter to match the properties of 3-phase Induction motor , the internal structure of the Inverter 1. Series converters (Converter Circuit), which acts. Convert AC power source AC. Power supply (50 Hz) to DC (DC Voltage) 2. Series inverter (Inverter Circuit), which convert DC (DC Voltage) to AC (AC Voltage. ) which can change the voltage and frequency 3. Control circuit (Control Circuit), which acts. Control of converters. And inverter working example of the inverter (Inverter) that are found in the electrical current to power back up. Also known as UPS (Uninterruptible Power Supply) to solve the overload, power failure, power failure and interference. Help prevent damage to electrical equipment. The electricity is stored in batteries that provide an example. If power outages UPS will switch to battery power immediately. Subsequently, the direct current electricity. Going into the inverter This will change the DC power into AC power at a fixed frequency and accurate AC power from the inverter will feed into the electrical machine. The AC power that comes out will be fed back to the comparison with a reference frequency value. Then the results of the comparison to control the generation of frequency inverters for AC power at a fixed frequency and accuracy. The electrical alternator want Inverter (Inverter) were used in electrical appliances such as air conditioners, refrigerators, televisions and servo motor control (Servo Motor) due to loss reduction task force. especially when starting work. And the loss in the core. And the coil (For welding equipment and motor rotation), which lost power or electricity as follows on appliances starts. Are the rumors started I (Start) higher while walking normally to 4-6 times as motors, air conditioning with a 220 V, 1 A Pnormal = 220V 1A = 220W as starting a motor or transformer will draw current to the field. Magnet least four times the normal time Pstart = 220V (4 1A) = 880W , making the old system that did not use the power inverter will be very high. And the level of voltage in the stable (Stable) including pressure Spike. While stopped, these will damage electrical equipment. Or impair the lifespan shorter sample problems and solutions. By the inverter (Inverter) used to run the air conditioning. The old system will work Intermittent often the fence. This creates problems with other electrical equipment. The high-power Thus bringing the Inverter to edit. Air motors work continuously make no stick - off. As in the old system The results proved that. "The motor runs continuously. It saves energy And the electricity over the weekend. And began to walk at least one double up, "which is the principle as to the status of work already. Series inverter is a motor more. (Faster) by increasing the frequency or modify the Duty Cycle and standby time. Or constant temperature Inverter will reduce the motor running down (slow down), but does not stop the motor. This reduces the power to use them Inverter for use in systems such as : 1. Use a backup power supply, called Stand by power supply or Uninterruptible Power Supplies (UPS) to replace the power supply. The main alternator failure 2. To control the speed of AC motors controlled by the widely-frequency AC voltage. To provide torque (Torque) constant speed changes every three. Convert power from the transmission of high voltage direct current into alternating current type. For services to users fourth. Blast system that uses an induced heat (Induction heating), which uses high-frequency AC voltage to operate.
