FAQs 6

Why does my inverter go into 'voltage-dependent power reduction' mode?

Why your inverter goes into 'voltage-dependent power reduction' mode In marginal cases your inverter may not trip off, but may reduce its power output instead as a way to cope with grid voltages that are a little too high. When your inverter reduces its power due to high grid voltages it is in what's called "Volt-watt response mode".

How to control AC voltage in an inverter?

Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage.

What happens if my inverter reduces its power?

When your inverter reduces its power due to high grid voltages it is in what's called "Volt-watt response mode". This feature is recommended in the latest version of Australian Standard AS4777.2 - and if your inverter has the feature, the standard mandates that it must be activated. I knocked out this sketch to show what happens.

How to reduce common-mode voltages in inverters?

The extra money involved in hardware-based common-mode voltage mitigation methods can be overcome by employing modification in the control strategy of inverters. Space vector pulse-width modulation (SVPWM) and modified SPWM are proven to be effective at reducing common-mode voltages in inverters.

How a voltage control inverter helps in achieving voltage variation?

In the case of variable speed drives, inverters with voltage control help in achieving voltage variation. Voltage control of inverters is employed in order to compensate for changes in input dc voltage.

Why are inverters used in motor control applications?

When inverters are used to feed such ac loads, it is necessary that the inverters provide provision for voltage variations so as to supply the required voltage to ac loads. In motor control applications, inverters handle the control of circuit voltage along with frequency so that the saturation of motor magnetic circuits is avoided.
