Electronics engineering for new designs, obsolete hardware and difficult failures
Micro Digital Engineering is an engineering company for power and control electronics in industrial equipment and new products. We take on complete development projects or defined engineering stages, agree deliverables and the verification method before work begins, and start with a paid first stage whose results guide what follows.
What does your equipment need?
Create a new electronic device
Turn an idea or a set of requirements into a development project: architecture, circuit design, firmware, prototypes and testing, with each revision checked against the agreed requirements.
Replace electronics that is no longer available
Assess an existing board or module and define a replacement around the functions, interfaces and compatibility your equipment needs, so the equipment can stay in service.
Resolve problems in an existing design
Investigate failures, overheating or unstable behaviour, identify the cause, make corrective changes and verify their effect under the agreed operating conditions.
Electronics engineering, from the complete device to the individual board
Custom Electronics Development
New devices from an idea, schematic or Gerber files to assembled, tested prototypes accepted against your specification.
Power Electronics Design
Power supplies, converters, inverters and drivers designed to agreed electrical and operating requirements.
Obsolete Electronics Replacement & Redesign
Compatible replacement or modernisation of boards and modules that can no longer be sourced.
Schematic & PCB Design
Individual control, power, measurement and interface boards.
Embedded Firmware & Control
Firmware for control, protection, measurement and communication. Existing firmware to recover or migrate: firmware reverse engineering.
Electronics Troubleshooting & Design Review
Failures, unstable operation, overheating and independent design review.
Functional Test Benches & Fixtures
Equipment that checks boards and power modules against acceptance criteria.
Power electronics as a core specialisation
Power conversion is at the centre of our engineering work: converters, inverters, gate drivers and the control and protection around them.
What we design
Power supplies and DC-DC converters
Isolated and non-isolated, dimensioned for the input range, load profile and efficiency target.
Inverters
DC-AC stages with their modulation, control and protection.
Gate drivers
Matched to the power semiconductors, switching behaviour and isolation.
Resonant and pulsed power stages
Where switching losses, voltage stress or pulse parameters set the constraints.
Agreed before design starts
- Input and output voltage ranges
- Power and load profile
- Efficiency and thermal limits
- Isolation and protection behaviour
- Control interface and operating environment
Prototypes are assembled, brought up and load-tested in-house to show whether the stage meets them.
How work starts
- Describe the task: what you need, what already exists, what is blocking progress.
- Discuss the scope.
- Agree a paid first stage.
- Review the result and decide what follows.
Tell us what needs to work
Send a short description of the device or equipment, its current state and the result you need.
Confidential task? We sign an NDA before you share technical files.
