12v power inverter Principle Power Inverter

Using a thyristor circuit to convert the direct current alternating current, this corresponds to a reverse process of the rectifier, the inverter defined. For example: AC power inverters‍ Application thyristor electric locomotives, so that when the downhill braking DC motor as a generator to run the locomotive's potential energy into electrical energy, trans go to the AC grid. Another example is the operation of a DC motor, to make it quick braking, the electric motor as a generator also allows operation of the motor kinetic energy into electrical energy, anti-delivered to the grid. 

The inverse DC into AC inverter circuit circuit called. In certain cases, the same set of thyristor rectifier circuit not only for, but also as an inverter. ‍

Converter in the inverter state, if the inverter AC side connected to AC power, the inverter converts DC to AC power with a frequency counter to go, called active inverter. If the change is not the AC side current grid connection, but directly to the load, which is a frequency inverter converts DC or AC adjustable frequency supplied to the load, then called passive inverter. AC frequency converter uses this principle to work. Except for Car power inverters‍ the active inverter DC reversible speed control system, but also for the exchange of spare lines rotor induction motor cascade control and other aspects of HVDC.

12 volt power inverters Car Inverter Introduction

Car inverter is designed for the production of small electrical appliances inverter, which is currently the most advanced DC - AC conversion of the product. The 12V DC vehicle into AC power inverters‍ a 220V AC provides commonly used, widely used in various electrical equipment, such as: mobile phones, laptops, cameras, camera, razor, air cleaners, current chargers and other electrical appliances. Is a car race, white, field work, travel, mobile office, special vehicles of essential goods, electric vehicle successfully solve problems.

12 volt inverter Car inverter Precautions

* Some chargers may be due to the converter outlet; 

* This product is DC24V car special, do not use in other voltages; 

* This product is a negative ground vehicle specific, positive ground vehicles can not be used; 

* This product is not applicable core transformer for 5W traveling charger. 

* May appear to "recharge" the former Pure sine wave power inverter‍ charging status indicator flashes red full off, the charging process becomes lit when charging. Red full off. This is a normal phenomenon. Does not affect the quality of any charge. 

* Some of the charger plug is inserted because of the direction that they can not work, this situation is to ask the conversion plug direction, then use.‍

12v power inverter Car power converter Cautions

Properly connected in the following order: 

1, start the car engine 

2, plug in the AC powered car (the case of switching off) 

3, open the car AC power switch 

4, plug in electrical AC power inverters‍ equipment 

5, after use, turn off the car AC power switch 

6, turn off your vehicle engine 

Avoid using vehicle power supply failed, inferior products may cause the principal burned car.‍

12 volt power inverters Principles and Applications of inverters in photovoltaic systems

1 . Requires a high efficiency. Due to the current high prices of solar cells , in order to maximize the use of solar cells, improve system efficiency, we must seek to improve the efficiency of the inverter .

2 . Requires a high reliability. Currently photo power sinverter‍ voltaic systems are mainly used in remote areas, many power plants unattended and maintenance , which requires an inverter circuit with a reasonable structure, strict screening of components and require an inverter with a variety of protection features such as input DC reverse polarity protection , AC output short circuit protection , thermal overload protection and so on.

3 . DC input voltage is required to adapt to a wide range, the terminal voltage of the solar cell and the intensity of sunlight varies with load changes , although the battery voltage of the solar cell has an important role, but because the battery voltage with the remaining battery capacity and internal resistance change fluctuate , particularly when the aging of the battery terminal voltage range is large, such as 12V battery , the terminal voltage may vary between 10V ~ 16V, which requires a larger inverter must be within the range of the DC input voltage vehicle power inverters‍ guaranteed to work , and to ensure that the AC output voltage stability .

12 volt power inverters Touch inverter terminals, especially with wet hands, otherwise it will cause electrical shock.

(4) For the normal operation of the inverter changes in their work environment, can not change its own connection should be a professional 

Or dealer to confirm the operation. 

(5) Do not put the battery Pure sine wave power inverter‍ into the fire, otherwise the battery will explode. And do not open or destroy batteries because batteries contain toxic to humans and harmful substances. 

(6) Minors must not use this product. 

(7) inverter operating environment should be well ventilated, temperature range -15 to 50 degrees Celsius environment, away from the fire source and the location out of direct sunlight. Not in the condensation, dust, high temperature operation in harsh environments. 

(8) Do not plug the inverter side of the blinds and do not use in the next heat source inverter (such as: electric heating, radiator, etc.) should be used in the shade. 

(9) When the machine is connected to the indoor power network, ensuring reliable inverter ground connection; diameter should meet the safety conditions of use, solar power inverter‍ if the diameter is too small, the line will become hot, it will lead to fires; cable do may be shortened.

12v power inverter inverter Features

1, the inverter output function:
After opening the car power inverter front panel of the "inverter switch", the upcoming DC battery power into AC rated voltage sine wave, and from the AC socket on the rear panel, the output terminals.
2, automatic voltage regulator function:
  When the battery voltage between points undervoltage and overvoltage point fluctuations within the rated power load changes, the machine has automatic voltage AC output function.
3, overvoltage protection functions:
  When the pure sine wave inverters battery voltage is greater than the "over-voltage point", the inverter will automatically cut off the AC output, buzzer alarm. Until the voltage drops to "over-pressure recovery point", the inverter automatically return to work before.
  4, undervoltage protection functions:
  When the battery voltage is below the "Brown-point", in order to avoid over-discharge and damage to the battery, the device will automatically cut off the inverter output. Buzzer alarm. Until the voltage rises to "voltage recovery point", the inverter automatically return to work before.
