Currently, I am using a 400V to 12V transformer in reverse, meaning I supply 12V and around 1.5 A to the secondary side of the transformator and try to get 400V output voltage. My problem is, when I connect anything to the primary side, my voltage breaks down, meaning I only get around 2V of input voltage and 60V of output voltage.
90kVA/90kW Modular, Scalable, 3-Phase Small-Frame Tower UPS. Supports 3-Phase 220/380V, 230/400V or 240/415V AC, 50/60Hz, Wye; Fully loaded maximum configuration. High efficiency on-line UPS with DSP/IGBT technology and 1% output voltage regulation. Pre-installed WEBCARDLX with latest version of PADM20 for enhanced remote management.
The full load current I (A) in amps is equal to 1000 times of transformer rating S (kVA) in kVA divided by the multiplication of root 3 times of line to line voltage V (V) in volts. I (A) = S (kVA) *1000 / (1.732 * V (V)) if you take the phase to neutral voltage V (L-N) in Volts means the current formula will be.
Well, what is the Line to-Neutral Voltage for this. It is 208 volts /1.732 which is 120 volts. The power is brought is as 208 volts 3 Phase and then the Line-to-Neutral Voltage will be 120 Volts. Each of the three Line-to-Neutral line will go to a part of the plant. When the lines were installed, the plant was divided into roughly 3 equal area
Applications that require this duty cycle modulation at fixed but non standard 50Hz or 60hz are mainly for the aerospatial industry. Airplanes use 400hz. The advantage of 400hz is that power transformers are less bulky than in 50Hz. There is also an industry need to adjust the inverter output frequency in real time.
