Harmonic current

Apr , 20 2024

What does harmonic current mean Harmonic current is a collective term for the sinusoidal components whose frequency is an integer multiple of the original periodic current frequency. A harmonic current with a frequency equal to k times the frequency of the original periodic current is called a k-th harmonic current, and all harmonic currents with a frequency greater than 1 are collectively referre...

Measures to suppress harmonics

May , 11 2024

The fundamental cause of harmonic generation is due to nonlinear loads. When the current flows through the load and does not have a linear relationship with the applied voltage, it forms a non sinusoidal current, resulting in harmonics. The suppression of harmonics in the power system is to reduce or eliminate the harmonic current injected into the system, in order to control the harmonic voltage ...

What are the characteristics of industrial UPS power supplies

Jun , 14 2024

Industrial UPS power supply needs to focus on the design of the ability to operate in high-temperature environments. Component design must be adapted to the operating requirements of industrial environments, high temperature and high humidity, but also to cope with corrosive gases on the corrosion of the system. Operating continuously at full load under a variety of operating conditions, industria...

Industrial and commercial energy storage system liquid cooling design

Jun , 14 2024

1. Industrial and commercial energy storage system liquid cooling design For the high-rate charging and discharging process of large-scale battery packs, the cooling capacity of air cooling system can not meet the heat dissipation demand of battery packs. Liquid has a higher specific heat capacity and higher thermal conductivity than air, and the liquid cooling cooling speed is faster, which has a...

What is the meaning of float charging for intelligent three‐stage charger in battery charger?

Jul , 12 2024

Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

What are Harmonics

Aug , 17 2024

1. Definition of harmonics In the AC power grid, due to the operation of many nonlinear electrical equipment, the voltage and current waveforms are actually not complete sine waveforms, but non-sine waves with different degrees of distortion. Harmonic refers to the amount of electricity contained in the current whose frequency is an integer multiple of the fundamental wave, and generally refers to...

Lithium battery life The reason for the slow charging speed

Dec , 13 2024

1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

Causes of harmonics in rectifier equipment

Mar , 21 2025

1. Nonlinear characteristics The diodes, thyristors and other power electronic devices in rectifier equipment have nonlinear voltammetry characteristics. Take the diode as an example, when the input AC voltage is in positive half circle, the diode is positive and the current can pass through; At the negative half cycle, the diode is reversed off and the current is almost zero. This characte...

Difference between transformer insulation class and insulation strength

Mar , 29 2025

Insulation level refers to the motor (or transformer) winding insulation material used in the heat resistance level. Motor and transformer insulation materials commonly used in the grade for A, E, B, F, H five. Each insulation level of insulation materials have corresponding limit allowable working temperature (motor or transformer winding the hottest point of temperature). Motor or transformer op...

How electrolytic capacitor work for industrial battery charger

May , 16 2025

I. What is electrolytic capacitor: 1. Electrolytic capacitor, as the “energy storage heart” of charger power module, bears the key tasks of filtering, voltage stabilization and transient response. Its large-capacity characteristics (up to tens of thousands of μF) can effectively absorb the pulsating current after rectification, reduce output ripple, and ensure that the charging process is stable a...
