Design around real power constraints

Electrical, thermal and mechanical decisions engineered together

Power electronics layouts must control current density, switching loops, heat, creepage and component stress at the same time. Excel Circuit coordinates stackup, copper weight, placement, routing, thermal strategy and manufacturability from the beginning—reducing risk before prototype build.

Core design capabilities

Engineering coverage for demanding power hardware

01

High-Current Routing

Trace width, copper weight, planes, bus structures and via arrays sized to reduce loss and temperature rise.

02

High-Voltage Spacing

Clearance, creepage, slots and isolation barriers planned around voltage, environment and applicable safety needs.

03

Switching Loop Control

Critical commutation loops kept compact to limit parasitic inductance, ringing and EMI.

04

Thermal Management

Heat spreading, thermal vias, copper distribution, heatsink interfaces and airflow constraints considered early.

05

Gate Drive & Sensing

Clean gate-drive paths, Kelvin connections and sensitive feedback routing protect stability and measurement accuracy.

06

DFM & Reliability

Fabrication, assembly, insulation, copper balance and test access reviewed before manufacturing release.

Design priorities

Practical controls for power density and reliability

Current Capacity
Copper cross-section, temperature rise, connector limits and transient loading evaluated together.
Voltage Isolation
Functional, basic or reinforced insulation requirements translated into board-level spacing and barriers.
Thermal Path
Loss sources and heat-flow paths coordinated with components, enclosure, heatsinks and cooling method.
EMI Control
Switch-node area, return paths, filtering and partitioning optimized to reduce conducted and radiated noise.
Mechanical Integration
Power terminals, heavy components, mounting, airflow and service access incorporated into placement.
