Uninterruptible Power System-Use of Inverters & Chargers

May , 09 2022

If you already have a pretty good idea about the available methods for converting ac power to dc power, an inverter covers the other direction: changing dc into ac. Normally, when we speak of an inverter, we mean a device that generates line frequency power from a dc source, to power conventional ac-powered loads such as a personal computer, or industrial controls and instrumentation. A UPS integr...

Do Ferro resonant chargers still have a place in battery charging?

Aug , 15 2022

One of the larger battery/charger companies selling chargers in the USA have announced that they are no longer manufacturing Ferro resonant chargers and have set 7/31/15 as the last date to accept orders.Is there something wrong with Ferro resonant charging that should make all charger companies follow that lead? Let’s consider Ferro resonant technology. The purpose of a Ferro resonant transformer...

Battery charging technology over view- Ferro resonant chargers

Aug , 15 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 andperformance of today’s industrial batteries. A battery charger is an electrical/electronic device that conv...

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...

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 ...

Why battery energy storage moving to higher DC voltages (Part-1)

Nov , 08 2022

Today, most utility-scale solar inverters and converters use 1500 VDC input from the solar panels. Matching the energy storage DC voltage with that of the PV eliminates the need to convert battery voltage, resulting in greater space efficiency and avoided equipment costs. The evolution of battery energy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Woo...

What is the basic operation of inverter?

Nov , 14 2022

What is an Inverter? An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 120 volts, or 240 Volts depending on the country. The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries which are charged...

8 Benefits Of Pure Sine Wave Inverters

Feb , 06 2023

When it comes to inverters, there are two main types to choose from. They are square wave or modified sine wave inverters and pure sine wave inverters. They each have their own features and advantages. You might tell from their names that the pure sine wave inverters are better in quality and performance. Of course, this doesn’t mean that the modified o...

Explanation of power terms related to UPS power supply

Jul , 28 2023

Transient recovery time: The time required for the output voltage to recover to the specified range when the load suddenly changes (0-100%, 100% -0%), usually in milliseconds (ms). Filter: A device used to eliminate noise, filtering the input or output to obtain pure alternating current. Shielding: A means of isolating and blocking electromagnetic radiation using physical principles...
