  • Fourier Analysis of input current of Single phase controlled bridge rectifier

    Fourier Analysis of input current of Single phase controlled bridge rectifier

    Aug , 29 2022
    While the use of uncontrolled rectifier circuits remains prominent, for some applications, more control and efficiency is necessary. This can be accomplished through the use of a controlled rectifier circuit in which thyristors connected in a full-bridge configuration adjust the average voltage. Each thyristor has a gate that controls when it turns on. With control circuitry these devices can be o...

  • Classification of inverters based on wave type (Modified Sine wave)

    Classification of inverters based on wave type (Modified Sine wave)

    Aug , 29 2022
    Modified sine wave inverter The output waveform of the modified sine wave (or corrected sine wave, quasi sine wave, analog sine wave, etc.) inverter has a time interval from the maximum positive value to the maximum negative value, which improves its use effect. However, the corrected sine wave is still composed of dotted lines and belongs to the category of square waves, with poor continuity and ...

  • Classification of inverters based on wave type (Pure Sine wave)

    Classification of inverters based on wave type (Pure Sine wave)

    Aug , 29 2022
    Power inverters can be mainly divided into pure sine wave inverters and modified sine wave inverters according to their waveforms. In fact, there is another type - square wave inverter, the earliest inverter, which is rarely seen now. Pure sine wave inverter The pure sine wave inverter outputs true sine wave alternating current without electromagnetic pollution, which is the same or even better th...

  • Single-Phase vs. 3-Phase Power Protection: What You Need to Know（part-2）

    Single-Phase vs. 3-Phase Power Protection: What You Need to Know（part-2）

    Aug , 29 2022
    What is 3-Phase Power? Unlike single-phase, 3-phase power produces three separate wave currents so there is no temporary absence of power. 3-Phase power delivers power at a steady, constant rate and can reach higher voltage levels up to 480V in the USA. This steady stream of power and ability to handle higher loads makes a 3-phase supply ideal for industrial and commercial operations. More Waves. ...

  • Single-Phase vs. 3-Phase Power Protection: What You Need to Know（part-1）

    Single-Phase vs. 3-Phase Power Protection: What You Need to Know（part-1）

    Aug , 26 2022
    Single-Phase vs 3-Phase Power Protection: What You Need to Know Power is power, right? Well not exactly. It’s true that most of the electrical power we use is alternating current (AC) power generated by utility companies. In fact, AC power is used to deliver the vast majority of the power to our homes and businesses. But AC power can be delivered in many ways, the two most common being single-phas...

  • What are the installation steps for the voltage stabilizer?

    What are the installation steps for the voltage stabilizer?

    Aug , 22 2022
    The voltage stabilizer is composed of voltage stabilizer and constant voltage, control circuit, and servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison and amplification, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted to mainta...

  • How a Voltage Regulator Works

    How a Voltage Regulator Works

    Aug , 22 2022
    All voltage regulators utilize the same technology to stabilize the output voltage. The output voltage is sampled (Sampled) through a resistor divider (Resistive Divider) connected to the inverting input terminal (Inverting Input) of the error amplifier (Error Amplifier), and the non-inverting input terminal (Non-inverting Input) of the error amplifier is connected to a reference voltage Vref. The...

    Battery charging technology over view- comparison among charger technology

    Aug , 22 2022
    Battery charging is a complex electrochemical process, in which the discharged electric energy must be replenished from the electric network. The quality of the charging process is critical to the health and longevity of batteries. As a result, battery chargers play a key role in the life and performance of today’s industrial batteries. A battery charger is an electrical/electronic device that con...
