It’s probably right because it’s clean and simple looking.

Arens’ automotive-hardened traction inverters with power ranges from 30 to 500 kW (40 to 670 hp) are for applications ranging from large transit buses and medium-duty trucks to hybrid passenger cars. With the Powerpac series, adapting an existing vehicle design to hybrid power does not involve intensive re-engineering. The Arens Powerpac 100-kW (134-hp) traction inverter features a high power density in a compact enclosure designed to fit with the battery, in the vehicle’s existing battery box. The inverter offers an insulated gate bipolar transistor-based design and is suitable for truck, bus, agricultural, and construction equipment applications. All Arens inverters feature cast enclosures sealed to IP67 with intelligent thermal protection.

Very much like what my team at SatCom came up with for the AIPM Advanced (or Automotive depending on the audience) Integrated Power Module. The switches are bolted to the base the bus bar connects across them with capacitors integrated as close to the devices as possible and the gate drive and controller board on the other major flat face. Doubt any of the Aren’s team ever saw anything we did, it’s just the most economic and sensible use of surfaces and volumes to get the best performance.
