● Diode all wave rectifying add IGBT chopping to replace SCR rectifying,it’s improving the power factor;The DC part and inverter part into one cabinet,which reduce the waterway and circuit between the cabinets,which is effectively avoiding the electrical interference and reducing the installation time.
● The inverter part is consisted of MOSFET single phase invert bridge in parallel style.Each bridge’s design power is 120kW/60kW.We adopt building block mode to pile up power,it’s very convenient to install and maintain because every single bridge board is designed as drawer structure consisted of slide way.
● We adopt matching transformer to realize power combination,also we adopt sub-resonance,no-welding transformer output mode and make resonance directly by tank resonance capacitor (low voltage) and inductor to achieve steel pipe welding power transmission by output lead.
● Use sealed box and install overhead air conditioning.
