Power and battery electronics, built to your spec
ChargeInfy designs custom SiC and GaN power converters, battery management systems for EVs and energy storage, sensor cards and auxiliary supplies, for research labs and industry teams that need hardware that fits.
Four product lines, each configurable or fully custom
Start from a validated platform and adapt it, or give us a blank specification. Every build ships with documentation, test results and firmware access where you need it.
WBG power convertersSiC and GaN
Bidirectional DC-DC (DAB, buck-boost), LLC and resonant stages, PFC front ends, and single- or three-phase inverters, including traction inverter prototypes.

Auxiliary power suppliesGate drive and control
Isolated gate-drive supplies with low coupling capacitance for high dv/dt switching, plus multi-output flyback and DC-DC modules for control boards.
- Isolation
- Low capacitance, high CMTI
- Input
- Wide range
- Outputs
- Single or multiple
Why teams choose ChargeInfy
Weeks, not months
Pre-validated platforms mean a custom design starts from proven layout, gate drive and protection, not a blank page.
Open where it matters
Accessible firmware, measurement points and full documentation, so researchers can modify and publish with confidence.
Built for fast switching
Layouts, supplies and sensing designed around the realities of SiC and GaN: tight loops, high dv/dt and fast fault response.
Local design and support
Designed and built in India, avoiding import delays and duties, with engineers who can support you directly.
From specification to working hardware
Specify
We agree ratings, topology, interfaces and test criteria with you.
Design
Schematic, layout, magnetics and thermal design, reviewed with you.
Build
Prototype fabrication and assembly with trusted partners.
Test
Bench validation, double-pulse and efficiency tests, with a full report.
Deliver
Hardware, firmware and documentation, followed by ongoing support.
