In inverters of electric vehicles, the power semiconductors consist of IGBTs, which are controlled by additional driver modules. In order to be able to dissipate the power dissipation of the IGBTs better, they are located directly on the heat sink. The challenge here is to maintain the best possible heat transfer and still have sufficient electrical insulation.
The nominal voltage range for LV inverters is 48V, using MOSFETs as power semiconductors. Due to the low operating voltage, the LV inverter is relatively inexpensive compared to an HV inverter, but very limited in terms of its maximum power. LV inverters are therefore primarily used for hybrid vehicles with a low electrical power in the range of 10kW to 20kW.

Inverter Software Architecture
Software Development for HV-Inverter
In order to estimate what memory capacity the controller requires and what computing power, a software architecture is essential. The starting point for good software is a clear formulation of the requirements and a clear definition of the interfaces to the hardware. Here we can support you with already existing modules, where only the parameters have to be adapted.
