Engineered for extreme thermal resilience, high power density, and continuous 24/7 reliability across Milan's demanding electrification infrastructure.
As Northern Italy’s undisputed economic engine, Milan and the wider Lombardy region are at the forefront of Europe’s industrial transition toward zero-emission transportation and heavy equipment electrification. Driven by stringent environmental policies including Milan’s Area B and Area C Low-Emission Zones (ZTL), the municipality has mandated aggressive decarbonization timelines. Public transit authority ATM Milano has committed to converting its entire fleet of over 1,200 buses to 100% electric propulsion by 2030, setting a benchmark for municipal and commercial fleet logistics across Southern Europe.
Operating heavy commercial vehicles, electric buses, emergency service fleets, and specialized industrial equipment within Milan presents rigorous technical demands. The dense urban architecture, coupled with severe seasonal temperature fluctuations—ranging from sub-zero Alpine winters to humid 40°C Mediterranean summers—requires onboard energy conversion systems engineered to operate under continuous thermal stress, high vibration, and unconditioned electrical supply lines. Standard commercial off-the-shelf (COTS) chargers consistently fail when subjected to these localized operational realities.
Information Gain Architecture: ABSOPULSE custom onboard chargers (OBCs) eliminate single points of failure by replacing conventional consumer-grade optocouplers with planar magnetic isolation, conservatively derated switch-mode topologies, and IP66/IP67 liquid or conduction cooling circuits designed specifically for Lombardy's industrial vehicle OEMs.
An Onboard Charger (OBC) serves as the primary gateway for transferring power from AC grid infrastructure (such as standard 400V 3-phase commercial connections in Italy) directly into a vehicle's high-voltage traction battery pack (300Vdc to 800Vdc architectures). Engineering a heavy-duty OBC capable of surviving decades of continuous service requires custom power conversion topologies that exceed generic automotive standards.
ABSOPULSE utilizes state-of-the-art Silicon Carbide (SiC) MOSFET switches configured in active Bridgeless Power Factor Correction (PFC) and isolated LLC resonant DC-DC converter stages. SiC technology drastically reduces switching losses, allowing switching frequencies above 150kHz. This dramatically shrinks the footprint of internal magnetics while achieving thermal-to-electrical efficiency peaks exceeding 96.5%. Higher efficiency translates directly into lower thermal dissipation inside sealed vehicle enclosures.
Industrial electrification requires robust galvanic isolation between high-voltage DC battery traction lines and low-voltage auxiliary control circuits (24V/12V). Our onboard power conversion platforms integrate high-frequency isolation transformers tested to withstand 4300Vdc breakdown limits. To satisfy stringent European electromagnetic compatibility directives (EN 55032 Class B and automotive CISPR 25), multi-stage active internal LC EMI filtering is incorporated natively into every design, shielding onboard sensitive CAN bus systems from switching noise.
Discover why tier-1 transportation builders, municipal utility engineering firms, and industrial machine builders specify ABSOPULSE custom onboard chargers.
Engineered to handle wide 3-phase AC utility swings (300Vac to 480Vac) and erratic industrial grid transients common in heavy manufacturing hubs around Milan, preventing nuisance shutdowns.
Fully encapsulated and potted against metallic dust, power washing, road salt, moisture, and extreme mechanical shock certified under IEC 60529 and MIL-STD-810G standards.

Our power conversion systems are deployed across diverse high-stress operational environments within Northern Italy. Each localized application demands tailored mechanical enclosures, dynamic electrical response, and strict compliance with EU technical directives.
Heavy electric transit buses operating along high-frequency routes (such as 90/91 circular trolleybus lines and central urban e-bus routes) rely on high-capacity auxiliary power units (APUs) and robust onboard chargers. ABSOPULSE custom DC-DC converters and onboard chargers step down high traction battery voltages to feed 24Vdc low-voltage steering hydraulics, door actuators, ticket validation machines, and onboard HVAC controllers continuous power without failure.
Logistics corridors connecting Milan to the Malpensa Cargo City hub, Segrate distribution centers, and the San Donato Milanese freight depots require commercial electric vans and medium-duty delivery trucks capable of rapid opportunity charging. Our 11kW and 22kW liquid-cooled onboard chargers integrate directly into vehicle chassis frames, allowing overnight or fast AC depot charging while resisting road debris, spray, and vibration.
Located near the epicenter of Italian automotive excellence, custom supercar prototyping houses, niche agricultural electric vehicle builders, and specialty material handling equipment manufacturers in Lombardy require custom form-factor chargers. ABSOPULSE provides fully tailored mechanical footprints, adapting input/output connectors, dimensions, and mounting brackets to fit constrained vehicle cavities.
