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.

1 to 50 kW
DC bus
Up to 700 V, 800 V on request
Switching
20 kHz to 1 MHz+, by topology
Protection

Sensor cardsIsolated measurement

Voltage, current and temperature sensing with signal conditioning matched to your controller's ADC, so measurements are clean from the first power-up.

Current
Hall, fluxgate or shunt
Interfaces
TI C2000, STM32, FPGA
Bandwidth
Specified to order

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

  1. Specify

    We agree ratings, topology, interfaces and test criteria with you.

  2. Design

    Schematic, layout, magnetics and thermal design, reviewed with you.

  3. Build

    Prototype fabrication and assembly with trusted partners.

  4. Test

    Bench validation, double-pulse and efficiency tests, with a full report.

  5. Deliver

    Hardware, firmware and documentation, followed by ongoing support.
