Design considerations
- Above ~400 V, selection is driven by efficiency vs switching speed vs cost, with SiC often preferred for high efficiency and high-frequency operation.
- Isolation and gate-driver robustness are mandatory - use isolated drivers or supplies with strong CMTI and dV/dt immunity, as switching nodes can exceed tens of kV/µs.
- Overvoltage and transient margins become a primary failure risk. DC bus spikes from switching and regen require higher voltage derating, snubbers and robust clamp / protection design.
- Safety, creepage, and fault handling drive system architecture. High voltage demands galvanic isolation, reinforced protection and fast fault response (DESAT/OCP) to protect devices and meet compliance.
