Description:
A Japanese electronics manufacturer is seeking research and development partnership opportunities in EU countries.
The company´s research area is power electronics.

Its research aims to miniaturize the power supply systems that are equipped in devices and control panels. While making the devices smaller they are attempting to maintain a power density of 2W/cc.

They are seeking a technology that meets their requirement for a compact and highly efficient switching power supply. They expect a partnership opportunity on joint research or commissioned technical development. They have no preference with regards to the size of the partner organisation.

Technical Specification or Expertise Sought:
The company is seeking an innovative technology to miniaturize a switching power supply that has a power factor correction circuit for industrial application.

They are mainly looking for the following three technologies:

1. Single stage converter technology of high frequency and high efficiency.
This is to achieve soft switching using a resonant circuit.
Reference article: "A Bridgeless Single-Stage Half-Bridge AC/DC Converter - IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 26, NO. 12, DECEMBER 2011"

The following points should be improved in this area:
- High voltage stress being applied to the switching device;
- Reduction of the ripple of output;
- Output holding time.

2. A technology that achieves a high frequency and high efficiency by soft switching with a power factor correction circuit of a buck converter system, and accomplishes high frequency and high efficiency with an insulation DC / DC converter (direct current to direct current).

The power factor correction circuit equipped with a buck converter system reduces the input voltage to approximately 100V DC from 90-240V AC. The insulation DC / DC converter should convert to the rated output of 24VDC.

3. An insulation DC / DC converter technology that operates at high efficiency and high frequency to achieve a power factor correction circuit technology and soft switching that can be applied to the amplifier circuit.

The company will consider partnership opportunities with those companies that are able to perform at least one of aforementioned three technological methods. The opportunity is not strictly limited to these three methods however, and the company will be flexible in assessing other methods of achieving the following specifications.

Specifications:
- Input conditions: 90 ~ 240V AC / Output voltage: 24V DC,
Rated output current: 5A = 120W, 10A = 240W, 20A = 480W
(one of the above three models or all)
- Size: Power Density 2W / cc or more (Including a noise filter)
- Efficiency: 120W: 91% or more, 240W: 93% or more, 480W: 95% or more
- Power factor: the rated 0.9 or more
- Temperature: at 60 ¿ environment (natural air cooling), none of the parts shouldreach the upper limit temperature. The temperature of the transformer and the choke coil is 115¿ or less.
- Noise: CISPR11 standards achievement of the class B
- Power retention time: enable to maintain the output for 20 milliseconds once the input is cut off.
- Output ripple voltage: 240mV (= 2% of the output voltage) or less. It must be insulated between primary and secondary.

Partner sought

Type and Role of Partner Sought:
