Description
The input range of 1500–3000 V DC matches high-voltage battery strings and traction networks, so the converter is placed between the DC bus and the 400 V network without intermediate stages. The five-level topology builds the output voltage from more levels than a two-level or three-level one, hence lower harmonics, a more compact output filter and lower losses in the power switches. The efficiency is 97 %. In charging mode energy goes from the grid to the battery, and in discharging mode it is returned back, so one unit works both as a charger and as an inverter. The power is increased up to 1 MW, so one platform is used both on a small storage unit and at a megawatt-class site.
How to choose
The choice starts with the DC bus voltage, which must lie within 1500–3000 V. Then the needed power for charging and discharging modes is calculated, and the upper limit of the platform is 1 MW. For low-voltage batteries of 48–220 V DC and powers up to 20000 VA the CS-IS inverters are appropriate, and for substation control power the DC POWER-L rectifiers of 10–800 A are suitable.
