What is the output voltage of the front stage of the power frequency inverter

How does a power frequency inverter work?

Its working principle is to convert DC power into AC power with the same frequency and phase as the power grid through an internal power conversion circuit. Power frequency inverters mostly use traditional components such as transformers and inductors to convert voltage and current.

What is a high frequency inverter?

In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.

What is the output waveform quality of a power frequency inverter?

Output waveform quality: The output waveform quality of power frequency inverters is usually better than that of high frequency inverters. Since the power frequency inverter uses traditional components such as transformers and inductors to transform voltage and current, its output waveform is closer to a sine wave and has lower harmonic content.

How do high frequency inverters produce a sine wave output?

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. For example, very narrow (short) pulses simulate a low voltage situation, and wide (long pulses) simulate high voltage.
