Technical FAQs 4

What is a high frequency inverter?

A high frequency inverter is a type of UPS (Uninterruptible Power Supply) that uses a microprocessor as its process control center. It employs software programming to control its operation, unlike traditional analog circuits.

What is a series inverter?

Series inverters are characterised by the load impedance capacitive at low frequency and inductive at high frequency. The transition frequency between being capacitive and inductive is the resonant frequency, a. at which frequency the L-C-R load circuit appears purely resistive and maximum power is transferred to the load, R.

Can a single-phase high-frequency isolated inverter prevent voltage spikes?

Finally, based on the special circuit structure of the isolated inverter, a single-phase high-frequency isolated inverter parallel experimental prototype is constructed, and the corresponding control strategy is presented. Experimental results show the excellent voltage spike suppression capability of the simplified active clamping circuit.

What is the difference between low frequency and high frequency inverters?

The low frequency inverters typically operate at ~60 Hz frequency. To produce a sine wave output, high-frequency inverters are used. These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time.
