The improvement of input circuit units, and the adoption of new high performance
components and the synchronous rectifying circuit contribute to high
efficiency. Compared to conventional products, efficiency is dramatically
improved by about 10%. Also the miniaturization and high power are achieved |

When we look at the existing systems
which are mainly used for server system, etc., we can learn that spaces
allocated to power supplies are very small, and existing full redundant
system seems to be almost impossible to achieve the reliability under
the circumstances where even smaller spaces are required. Paradoxically
speaking, the existing redundant system seems to be required to cope
with poor design that reduces reliability and causes many power accidents.
However, providing that smaller space requirement still remains, essential
solution to raise the reliability comes from efficiency improvement and
hot-swappable structure to make primary part redundant which has high
rate of component damage. This is what we thought. Additionally, other
possibility of damage can be prevented by simple circuit method to reduce
components and component selection with more margin to derating rate.
Moreover, as circuit design innovation and policy, we have adopted parallel
circuit system rather than series system such as parallel use of smoothing
capacitors for safer circuit structure.
Following is the detailed differences and features of our system. Difference
between existing system (full redundant) and Primary redundant system
|

Primary redundant system
(Nipron system) |
Existing full redundant power supply
(Power supply without enough space) |
| Efficiency |
- Power loss of mutual interference diode is several wattage or less
as it is mounted in primary side.- As secondary side is in common, component
size is one rank or two larger to contribute to higher efficiency due
to lower resistance (77% typical at AC 240V). *Our new product achieves
high efficiency 85% typ at AC 240V.
|
- As Oring diode for parallel operation is mounted in each main output,
power loss is 10W to some 10W to raise temperature and reduce efficiency
of the power supply.- With components squashed up in a small space, power
loss caused by chokes or electric capacitors is large. |
| Simplicity of circuit and number of components |
- Number of components is fewer as secondary side is in common, and it
has margin in component size to keep clearance between them. Also it has
large derating of part rating. |
- Same secondary circuit is doubled to meet full redundancy to increase
components and likely to cause mutual touching of components. |
| When one unit of redundant unit fails |
- By making secondary side in common and having enough margin in components,
even one primary unit can afford continuous full power with no problem
including primary unit components. |
- With load sharing between 2 units, when one unit fails, the other unit
has to burden all output power limiting long time operation (one hour or
longer) as thermal design has no margin. |
