Power Inverters

Technological analysis:
From a simple construction analysis (benchmarking) to a criticalanalysis (process, design) using our database and our knowhow.

Component choice
Serma can help the customer to do the right trade-offs through construction analysis results, crossing database information (guideline), and drive qualification plans

Problem solving (failure analysis)
Based on our component experts experience

Robustness, Screening, Qualification, Reliability test plans
Our ETM BU can define all those type of tests (according the component choice, the mission profile, etc.)

Test achievement:
Our lab can run tests using its equipments, and coach or
subcontract mechanical tests (vibrations, shocks)

An expertise centre from the bare die to the system

Electrical tests & characterisation Development of test solutions  Go / No Go Test, Up-Screening (7000 programs) Parametric characterisation (AC/DC, functional) Customized evaluation (non-standard specifications ----ESD, Latch-up, Electromigration

Environmental tests Thermal cycles shocks Temperature & humidity Pressure Cooker & Hast High-temperature storage, Burn-in, HALT, HASS
Power Cycling Test System
Possible electronics under test : Diode, MOSFET, IGBT, etc. Main characteristics: ---1 to 20 DUT (Device Under Test) ---Maximum Power available: 12kW (20V, 1200A)Switching ---frequency (for MOSFET/IGBT) : up to 10kHz ---Cycles controlled in: ------time (set tON and tOFF) ------or temperature (set TMAX et TMIN) ---Air cooled Aluminum heat sink Evolution 1 : ---DUT mounted in a climatic chamber (T and RH) Evolution 2 : ---DUT switching high voltages and high currents (high capacitance capacitor discharge), to be as close as possible to the mission profiles
6 constraints can be combined (under conditions) : ---Temperature and deltaT -------70°C / +200°C (>±10°C/min) ---Relative Humidity ------10% to 98% at Patm ; 10% à 95% at 91mbar ---Vacuum ------Patm down to 20mbar ---Voltage, current ------6kV, 2A ------10V, 1000A ------330V, 30A (x2)
