Hanfong Car power inverter manufacturing process

1. HF Power Inverter made SMT chip technology, what is the SMT chip process?

"SMT" is called "automated programming machine" and "patch" is actually a form of encapsulation of RC components.

High precision, small size, high degree of automation, good reliability of component welding, YL power inverter is through

SMT to achieve product processing and production.

2. What is a microcontroller?

The YL Power Supply with high and low voltage alarm, protection and other parameters and functions is implemented by the CPU microprocessor.

Inverter models are called single-chip type.

3. What is a simulator?

By separating the components to achieve the YL power inverter features a variety of parameters of the model, known as the simulator.

4. What are the performance characteristics of YL power inverter?

The YL Power Inverter converts DC12V to 220V. It has the following functions:

1) Input high voltage, low voltage alarm and protection.

2) Overload protection.

3) Instant impact 2 times rated power.

4) Overload and short circuit protection.

5. What is the working principle of YL power inverter?

PWM pulses are realized by the YL microprocessor, and the low voltage 12V is changed to about 300V DC by the high frequency transformer.

Press. Then the CPU outputs a 50 Hz AC drive signal to drive the power switch. Through the power tube

Through the conversion, to achieve the output square wave form of the average effective value of 220V AC voltage.

6. Is the output voltage of the YL power inverter stable?

The output voltage of the CRT power inverter is confirmed by its own feedback to stabilize the voltage. No-load and rated power

Change in pressure value is less than 10V.

7. How to determine if its stable value is safe for users?

YL power inverter fully considers the external use environment, YL power inverter when overload or short circuit occurs

Will automatically protect the shutdown.

8. What is the output frequency of the YL power inverter and what is its output frequency?

The output frequency of the YL power inverter refers to the period of the output AC square wave. Its frequency is 50 Hz. The national power supply standard

The standard is 50 Hz. In general, the period is 20MS, F=1/T=50HZ.

9. What is the continuous output power?

The continuous power refers to the power of the YL power inverter that can operate continuously under normal conditions.

10. What is the peak output power?

The peak power refers to the power that the YL power inverter can withstand at the moment of starting. It usually refers to the load of the motor type.

When the start-up current due to a large starting current and the formation of the instantaneous power, known as the peak output power.

11. What is the difference between the continuous output power of the YL power inverter and the peak output power?

The continuous power and peak power vary depending on the meaning of their expression.

Continuous load = current value × 220 (AC voltage)

Start load = 2 × power value

In general, the starting load of an appliance or power tool determines whether your power converter has the ability to drive it.

12. What is an inductive load?

Under normal circumstances, it is common to load a load with inductance parameters, that is, a load that meets the characteristics of the current lead voltage.

Sensual load.

13. What is a capacitive load?

Generally, the load with capacitive characteristic parameters, that is, the load that meets the voltage-advance current characteristics, is called capacitive negative.

Loaded.

14. What is the difference between inductive and capacitive loads?

Different load characteristics. First of all when selecting the load must meet the YL power inverter rated power. As long as the

YL power inverter use conditions, its capacitive and inductive load effects are the same.

15. What is the difference between the output waveform of the YL power inverter and the 220V output voltage?

The output of the CRT power inverter is an analog sine wave, and the mains power is a true sine wave.

16. YL power inverter output waveform and the output voltage is 220V What is the difference?

The 220V voltage output from the CRT power inverter is exactly the same as the market voltage.

17. Is YL power inverter only suitable for 11-15V input DC voltage?

CRT power inverter can only be applied to 11V-15V input DC voltage.

18. Is it above or below this output value applicable and work?

Below this input value, YL power inverter sends a low voltage alarm, please pay attention to the power load. When the input voltage is low

, YL power inverter is automatically protected. Above this input value, YL Car Power Inverter will automatically protect when

If the input voltage is much larger than that, the power element of the YL power inverter will be damaged.

19. How to understand the conversion efficiency of YL power inverter?

The conversion efficiency of YL power inverter generally refers to the ratio of the output power and the total input power.

The higher the efficiency, the better.

20. What is the no-load current value of YL power inverter?

The no-load current refers to the current consumed by the YL power inverter without load.

twenty one. What is the main function of cooling fan of YL power inverter?

The cooling fan of the YL power inverter is mainly used for heat dissipation. The air is convected by the side plate fan to make air convection.

Power inverter power components operate in a safe temperature environment, Solar Inverter .
