Overview of the power source
The ever-increasing use of non-liner electrical and electronic
devices or apparatus has caused great harmonics to power grid which
affect the normal work of sensitive-loads or even cause damage,
especially for sensitive load. To solve these kinds of power
quality issues, the most effective way is to adopt purified AC power source which work with load in series and controlled by DSP like a
controlled power source when it works. Its core part is IGBT
controlled by PWM. It outputs power of pure sine wave and supply
power for connected load. This kind of purified AC power source, also called power quality controller, can solve voltage
flickering, voltage sag issues and deal with unbalanced voltage
(L-N). In this way, it can supply power of pure wave and balanced
voltage to connected load. Our purified AC Power source is widely used in telecom industry, geological exploration, medical
industry, railway and mining industry where it need supply good
Features of power source
· Improve power quality notably by dealing with all main factors
concerning power quality.
· Eliminate harmonics, voltage fluctuation, flickering as well as
deal with unbalanced voltage (L-N) and low power factor.
· Instantaneously compensate voltage and quick response time.
· Voltage: 380V, frequency: 50Hz, 3 phase 4 wires.
· Power per unit: 0.5KVA～750KVA(Can work in parallel operation)
· THD of input voltage<30%, THD of output voltage<5%.
· Protection function: Over-current, over-heated, over-loaded and
over-voltage protection for the inverter(IGBT).
