The difference between AC variable frequency power supply and inverter:
AC variable frequency power supply is to convert AC power supply into DC power supply, and then convert it into AC power supply that can only change within a specific frequency range.
Inverter usually refers to how to convert low-voltage DC power into high-voltage DC or fixed-frequency AC.
The difference between AC variable frequency power supply and inverter mainly depends on whether the voltage change before and after use is large. If it is large, it is an inverter.
What is AC variable frequency power supply?
AC power supply is a dual inverter with AC-DC-AC conversion function. Its main function is to convert the 50Hz AC generator in the current system into AC of different frequencies. The output waveform is a stable pure sine wave, and the output voltage and frequency can be adjusted within a certain range. Its characteristics are stable pressure, wide stable range, wide frequency, high density, light weight, small size, good waveform quality, good output of separation transformer, and high load.
Working principle of AC variable frequency power supply
The working principle of AC variable frequency power supply: It is also applicable to other electrical equipment. It has certain requirements for environmental use. Factors such as ambient temperature, humidity, dust, acid and alkali, corrosive gas, etc. should be considered. The most effective energy-saving measure is to use the inverter to control the flow rate. Using the inverter (electrical rate 20 50) to save energy has achieved remarkable results.
Due to technical specifications, many machines require motors that can control speed. In the past, DC control required speed control while AC motors tried to control speed. However, the design of DC motors is complex, cumbersome and difficult to maintain. Therefore, with the development of speed control technology, AC control has gradually replaced DC control, and direct vector torque control is usually required to meet the preparation requirements.
What is an inverter?
An inverter, also known as an inverter power supply, is a current converter that converts 12V or 24V DC into 240V, 50Hz or other types of AC. The output current can be used in mobile power supply areas or various devices to meet the needs of users without power supply.
With an inverter, it is possible to convert DC power (batteries, circuit breakers, fuel cells) into AC, so that electrical devices such as laptops, mobile phones, digital cameras, etc. can be reliably and reliably protected. Inverters are increasingly in demand for wind and solar power generation. Small inverters can also provide AC power for cars, boats and portable appliances on site. )
