Product Description
product description
The VSPS series of high-voltage shore power supplies use power unit series technology and directly output 6.6KV or 6KV. 36 pulses on the input side
Rectification technology, low harmonic pollution on the grid side, high power factor. No harmonic interference to other equipment on the grid. The output side is
With multiple sine pulse width modulation technology, the output harmonics are also very small. The main controller adopts 32-bit floating-point DSP digital signal processing
The core is very large-scale integrated circuit (CPLD and FPGA), which is composed of data acquisition, unit control and optical fiber communication loop
System control part.
System principle
The principle of superposition is similar to the "battery stack superposition" technology. When 6.6KV output is required, 6 power units are connected in series per phase. The effective AC output value of each power unit is 634V, the phase voltage is 3810V, and the line voltage is 6600V. Each unit can output up to 690V voltage, and the system can output up to 7170V.
System Components
The typical VSPS series high-voltage shore power supply mainly includes: incoming line current limiting cabinet, phase-shifting transformer cabinet, power unit cabinet, control cabinet, and isolation transformer cabinet.
