What Converdan does

Converdan A/S is a privately held Danish power electronics manufacturer founded in 2011 by Thomas Slivsgaard, headquartered in a 3,900 m2 facility in Vojens, Denmark. The company designs, engineers, and manufactures AC/DC active front end (AFE) modules and DC/DC converters — bidirectional, grid-connected power converter building blocks covering 500W to megawatt-scale systems — targeting DC fast charging, battery energy storage, renewables, and demanding industrial OEM applications. Its standard product catalog includes 33kW and 35kW AFE modules (air- and liquid-cooled, scalable to 1MW+) and 50kW isolated bidirectional DC/DC and 500W high-voltage DC supply modules, all built around proprietary DSP-based control platforms and CAN-bus master-slave paralleling architectures, with full in-house PCB assembly, box-build, and burn-in meeting IPC610 standards.

The company operates a dual business model: sale of standard 'ready-to-wear' converter modules (over 100,000 units deployed in the field) alongside bespoke OEM co-development and EMS manufacturing services, supported by an integrated product-development capability spanning hardware, converter control, embedded software, mechanics, and EMC/safety compliance. Revenue is generated through quote-based direct enterprise sales led by a Sales Manager and Business Development Manager with application-engineering support; pricing is not publicly disclosed. Converdan holds certifications across UL, CSA, EN, CE, VDE, TÜV SÜD, and IEC standards supporting both EU and North American market access.

Customers are worldwide OEMs in e-mobility, renewables, industrial, power quality, and power-supply verticals, with disclosed long-tenured relationships including Vetaphone (since 2011), Orbital A/S (since 2014), and Evosep (since 2017). The company ships 800MW of converter capacity annually against nameplate capacity exceeding 3GW, is co-funded by the European Union on battery-storage initiatives, and received three consecutive Børsen Gazelle awards (2018–2020) for growth. As of early 2026, Converdan employs approximately 40 people and is run by founder Thomas Slivsgaard (CEO/CTO) alongside COO Rasmus Pedersen, CFO Tim Damgaard-Vyum, R&D Manager Poul Kristian Nielsen, and Sales Manager Jørgen Grønlund.

Revenue model

1. Power Electronics Hardware Sales: Converdan generates the majority of its revenue from the sale of power electronics hardware — both standard off-the-shelf converter modules (AC/DC and DC/DC) and custom-designed OEM products. Production volumes range from hundreds of units for niche applications to tens of thousands annually for high-runner products.
2. Custom Product Development Services: Converdan offers full-cycle product development services — from concept and prototyping through to production-ready design — spanning hardware, embedded software, control algorithms, mechanics, and EMC/safety compliance. This is bundled with manufacturing as an integrated offering.
3. Manufacturing Services (EMS): Electronics manufacturing services including PCB assembly, box-build, panel shop, test & burn-in, and repair/rework — available as standalone services or integrated with product development. Covers volumes from low-mix low-volume to multi-year high-volume OEM production.

Core offering

Converdan A/S engineers and manufactures power converter modules (AC/DC active front ends and DC/DC converters) and provides custom power electronics design and EMS manufacturing services. Its standard and bespoke converter products — ranging from 500W high-voltage DC supplies to 50kW bidirectional DC/DC modules and 33–35kW grid-connected active front ends scalable to 1MW+ — are sold to OEM customers in DC fast charging, battery energy storage, renewables, industrial, and power-quality applications.

Product overview

Converdan offers "ready to wear" off-the-shelf standard products targeting DC Fast Charging and Energy Storage markets, with over 100,000 units deployed in the field. The AC/DC product line comprises three Active Front End (AFE) modules: the 33kW air-cooled AFE333KAC (4RU), 33kW liquid-cooled AFE333KLQ (5RU), and 35kW AFE335KAC—all bidirectional grid-connected rectifiers scalable to 1MW+ systems. The DC/DC portfolio includes the 50kW CDC350KAC isolated bidirectional module and 500W CDC150HV high voltage DC power supply (600-950V input). Beyond standard products, Converdan provides custom design services ranging from adaptations to fully customized OEM solutions, supported by in-house product development (hardware, control, software, mechanics) and manufacturing capabilities (PCB assembly, box-build, testing) from their 3900m2 Denmark facility.
