A voltage converter 12/220 usually refers to a device that can convert 12 volts direct current (DC) to 220 volts alternating current (AC). This converter is also called an inverter. Its main function is to convert low-voltage direct current (usually from a car battery, solar cell or other DC power source) into high-voltage alternating current […]

A DC/DC converter is a power electronic device used to convert one DC voltage to another. It plays an important role in many electronic systems, especially in power management, renewable energy systems, and portable electronic devices. The main function of a DC/DC converter is to provide a stable output voltage by regulating the input voltage,

The process of converting alternating current (AC) to direct current (DC) is called rectification. The main method of rectification is by using a rectifier circuit, which uses semiconductor components (such as diodes) to convert the alternating positive and negative parts of the alternating current into a single direction of current. What is alternating current? Alternating

What is a variable frequency drive? A VFD is a device that changes direct current into adjustable frequency alternating current to control motors. These VFDs not only convert the power, but also boost and condition it before sending it to the AC motor. VFDs do this by changing the magnetic field on the stator and

Single-phase or three-phase power refers to the power that comes into your home, either underground or via an overhead street power source. Most homes typically use single-phase power. Three-phase power is typically used in commercial/industrial settings and large homes with multiple large appliances that draw a large current. If your home draws a lot of

The high-voltage inverter has a highly intelligent computing level and a complete fault detection circuit, and can provide precise positioning of all faults and give clear instructions on the main control interface. In actual applications, we found that common faults can be divided into control channel abnormalities, IGBT overcurrent, overvoltage faults, etc. Here we analyze

During the use of high-voltage inverters, it is inevitable that they will suddenly shut down for some reasons. After the high-voltage inverter is shut down, a series of inspections and maintenance are required to ensure the safety and reliability of the equipment. Shutdown is not terrible, but how to maintain the inverter after it is

A frequency converter is a device that converts AC power into adjustable speed DC power, and then converts DC power into adjustable frequency AC power. The main components of the frequency converter include rectifier, intermediate circuit, inverter and control circuit. Small frequency converters are widely used in industry and homes to control the speed and

Before the frequency converter adjusts the water pump pressure, we must first understand the working principle and performance parameters of the water pump. A water pump is a device that converts mechanical energy into liquid pressure energy. Its working principle is to use the rotation of the impeller to generate centrifugal force to suck the

SPWM (Space Vector Pulse Width Modulation) is a pulse width modulation technique used in power electronic converters (such as inverters). It generates drive signals through the space vector method to control the operation of the motor, and is usually used in AC motor drive systems. SPWM has higher efficiency and better output voltage waveform than
