48V inverter design solution

Which inverter is best for a 48v battery?

In the 48V case, transistors and drivers that can handle at least 100V on the power nodes are a good choice. In a mild hybrid application, realizing the most efficient use of battery power is one of the keys to meeting miles-per-gallon (mpg) and CO2 emission targets. An efficient inverter starts with transistor selection.

What is a 48V 12Kw inverter of BSG?

A 48V 12kW inverter of BSG was designed with paralleled TO-Leadless MOSFETs. The phase current was up to 500Arms while the VDS voltage spike was under 70V. The maximum temperature rise of MOSFET was 30°C, and the current of MOSFET was balanced well. This design fulfilled the power requirement with 105°C liquid cooling system.

What is a 48 volt power supply?

Infineon stands for the introduction of the 48 V power supply and already offers an extensive application and product portfolio for 48 V solutions in electric and mild hybrid cars. Traditionally, battery electric vehicles (BEVs) have been equipped with a high-voltage (HV) power supply and a 12 V power supply.

What is inverter specification?

The inverter specification describes the working condition of the power stage as shown in Table 2. This specification is not directly limited by the power stage. The power stage is designed for such inverter and motor system. The target motor is Permanent Magnet Synchronous Motor (PMSM).
