Effect of input capacitors between UPS and Generator

Jul , 18 2022

Input capacitors used for filtering purpose cause pure apparent power to flow between the supply and the UPS. Such power is referred to as leading or capacitive power. Gensets can manage limited amount of pure leading power, as it interferes with the excitation circuit in the AC generator, leading to voltage oscillations and genset’s shutdown. Safe operating area charts show the allowed gensets’ l...

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. ...

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...

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...
