In this paper, the principle, function, type and application of inverter switch are introduced in detail. The inverter switch plays an important role in inverter circuits, widely used in solar inverters, air conditioning inverter and other fields.
1. What are the inverter switches
The inverter switch is the part that controls the on-off of inverter circuit. It controls the conversion frequency and direction of the transformer, so that the input direct current can be converted into the required AC power output to the load.
The inverter switch is composed of multiple field effect tubes or IGBTs, which can achieve high efficiency, high frequency and high performance inverter control. Easily achieved in power inverter 3000w.
2. How does inverter switch work
An inverter switch is an electronic device used to convert direct current to alternating current. An inverter switch usually consists of multiple transistors or Fets, where the state of each switch (on/off) is determined by a control signal.
Through the control of these switches, an inverter like 2000 watt inverter pure sine wave can modulate the direct current and convert it into an alternating current output. In the inverter, the role of the switch is to convert direct current to alternating current.
Generally, the inverter switch is composed of three parts: transmission components, controllers and fuses. Among them, transmission components refer to power converters, output inductors and other components.
The controller plays the role of controlling the switching state. Such as deciding when to switch on and off, and switching frequency. The fuse is used for safety protection against switch overload.
3. What are the types of the inverter switch
According to the working principle of the switch, an inverter switch can be divided into the following two types:
● Soft switching
Soft switch can effectively control the loss of components, improve conversion efficiency, but also reduce electromagnetic interference. In general, the circuit structure of the soft switch is more complex than that of the hard switch, and the operation is also more demanding, and the cost will increase accordingly.
● Hard switching
The circuit structure of the hard switch is relatively simple and the operation is easy. However, due to the instantaneous short circuit in the switching process, the current will change sharply, and it is easy to produce noise and voltage fluctuations. At the same time, it will increase the loss of the circuit.
According to the inverter mode can be divided into two categories: diode inverter and transistor inverter.
- Diode inverter is by connecting the power supply and the load through the diode, using the diode on and off to convert direct current to alternating current.
- Transistor inverter is to modulate and convert direct current by using multiple transistors as switches.
4. What does an inverter switch do
What does an inverter switch do The inverter switch is the core component of the inverter circuit. In the inverter circuit, the role of an inverter switch mainly has the following two aspects:
- Conversion of direct current to alternating current
The inverter switch can convert direct current into alternating current. In the inverter circuit, the direct current is modulated by inverter switch and converted into an alternating current output.
- Control output voltage and frequency
The inverter switch can adjust the output voltage and frequency by controlling the switching state. By controlling the on/off state and time of each switch, the output voltage and frequency can be adjusted to meet the different needs of different occasions.
5. The difference between the inverter cathode and the switch
- Inverter cathode
The cathode of inverter is one of the output electrodes of the inverter. The PV inverter converts direct current into alternating current and outputs it to the load, and the cathode is the cathode that outputs alternating current.
It is generally connected to the output port of the inverter and connected to the load. The function of the inverter cathode is to output the current after the conversion of the inverter to provide the required power for the load.
Although the cathode and switch of inverter are important components of inverter circuit, their functions and roles are not the same. The cathode of the inverter is the electrode that outputs alternating current and transfers the converted current of the inverter to the load.
The inverter switch is to control the AC direction and frequency of the circuit to achieve the conversion from DC to AC. The cathode and the switch play different roles and functions in the inverter, but they are closely related.
In short, the cathode of the inverter and the switch are important components in inverter circuit, which respectively play an important role in the circuit output and control. The cathode of the inverter is responsible for the output current and provides power to the load.
The inverter switch is the on-off of the control circuit to achieve the conversion of direct current to alternating current. Understanding the difference between the cathode and inverter switch helps us to better grasp the control technology and application of inverter circuit.
6. What are the applications of inverter switch
Inverter switch is widely used in various occasions. Common application areas include:
- Solar inverter
Inverter switch is widely used in solar inverters. The inverter switch can convert the direct current output of the high efficiency solar panels into alternating current, which is used in home energy storage to power household appliances or commercial equipment.
- Air conditioning inverter
Inverter switches are also widely used in air conditioning inverters. By adjusting the output voltage and frequency, inverter can realize precise control of the air conditioner and improve its performance and energy saving effect.
7. Conclusion
In summary, inverter switch is a very important part of inverter. Its role is to control the current and convert the voltage. Different types of switches have advantages and disadvantages; choosing an inverter switch that suits your needs is very important, and needs to be considered comprehensively.
