Technical FAQs 4

What is a pure sine wave inverter?

Rugged, heavy duty and industrial grade 3-phase pure sine wave DC/AC inverters, 24V, 48V, 125V or 250VDC inputs available. 208VAC or 380VAC or 415VAC output, 60Hz, 50Hz, or 400Hz, 9000 watts. Pure sine wave output exactly duplicates mains power. Extra heavy filtering to isolate noise from equipment sharing the same battery

What is a high efficiency Vienna Rectifier?

This high efficiency Vienna rectifier is designed for several end applications such as electric vehicle (EV) and industrial battery chargers, and industrial equipment requiring very high PF and low THD. You might also like...

Which diodes are used in the Vienna Rectifier?

In the Vienna rectifier, we selected SiC diodes with a blocking voltage of 1.2 kV and 30 A, rated for D1 and D2, and 60-mΩ and 650-V SiC metal-oxide semiconductor field-effect transistors (MOSFETs) for Q3 and Q4 (see Figure 40). Switching at 95 kHz achieved the target loss. Figure 40.

What is the difference between T-type converter and Vienna Rectifier?

The T-type converter and Vienna rectifier have higher eficiencies compared to two-level converters because the switches are presenting lower switching losses thanks to the half switching voltage. At higher loads, the T-type converter shows superior performance thanks to the synchronous rectification feature.
