Headspring Inc.

Supporting commercialization
with power conversion module
and advanced control technology.

As power electronics are expected to grow in the future, more companies are entering new businesses. On the other hand, power electronics is a complex field and requires a high degree of reconciliation.
Our engineers, who are familiar with power electronics, incorporate the most advanced elements of power electronics into the technical assets of our customers and provide comprehensive support from specification to development management of the entire system. We support the commercialization of various power electronics-related products that utilize customers’ existing technical assets.

Regenerative DC power supply/electronic load

Regenerative DC power supply/electronic load suitable for evaluation of motors, inverters, converters, etc.
It is an energy-saving power source that not only generates power as a power source but also regenerates power when the motor decelerates, and has little energy loss.

Overview

A regenerative type DC power supply/electronic load that combines the functions of a DC power supply and an electronic load. Large capacity can be achieved in parallel, and up to 30kW can be configured.
It also has a LAN communication function that can be controlled from a PC and used for a wide range of evaluation tests.

Specifications

Rated capacity± 5kW (with regeneration)
Rated input voltage three-phase200V
Output rated voltageDC500V
Output current rating30A
Parallel connectionpossible (up to 10 units)

Technical assets to use

- Power conversion module (SiC)

Evaluation test system for manufacturing equipment

Along with the expansion of demand due to EV shifts, there is a need to change manufacturing facilities. In consideration of the LCA (Life Cycle Assessment) of EVs, we will build an optimal evaluation system for reducing energy during manufacturing.

Overview

Characteristics

- A single system can output up to 500kW or 1000V/1000A
- Maximum 4000A output in 4 parallels
- Supports various communication interfaces such as CAN BUS, MOD-BUS, Ethernet, etc.
- Battery and motor simulation tests are possible by program

Applications

- Energy-saving battery cycle evaluation test
- Battery simulation test for EV powertrain development
- Inverter/converter performance evaluation

Instantaneous voltage drop compensation device

In production lines such as automobiles and semiconductors, power backup equipment such as UPS and voltage sag compensator is necessary to prevent equipment from shutting down due to momentary voltage drop due to lightning surge. We are developing and systematizing such internal power converters for
backup power supplies.

Development results

An industrial backup power supply has been developed.
Functional prototyping
- Prototype construction with our products

Mass production prototype
- Redesign of hardware
- Diverting software developed in functional prototyping.

*Product development time is greatly shortened by the above process.
