Enable traction inverter design flexibility with our multipurpose, automotive-grade PWM controllers, which facilitate the creation of reliable, high-performance powertrain solutions
The implementation of high-voltage batteries in electric vehicles requires efficient power supplies that can generate low-voltage rails. These rails need to be generated from either low- (12 V to 48 V) or high-voltage (400 V to 800 V) batteries to ensure high traction inverter reliability.
Our PWM controllers:
- Handle wide input-voltage ranges to support rail generation from low- and high- voltage batteries.
- Support isolated (flyback, forward) and nonisolated (buck, boost, SEPIC) topologies for flexibility.
- Can use either Si or SiC FETs for further powertrain efficiency and reliability.
