现在这个领域还有什么方向或者topic可以值得做吗？ |

high switching frequency? |

发帖数: 40 | 3 High switching frequency frequency is very hard to follow, especially now
there is a 500MHz one from Intel.
Are there any topics that would be recommended? or dc-dc converter for
different application, which is novel.
Thank you, |

试发明个极高频损失很小的变压器之类。 |

multiple outputs; sub-threshold controller etc. |

发帖数: 1035 | 7 sure.. above 10kw, below 1w; don't touch the mid range unless you can reach
97% efficiency

any way, i like the analog device isoPower gate drive with isolated dcdc but
its wattage is too low to drive large switches.
reduce cost and size is important in power electronics. if you can integrate
a protected gate drive circuit that is helpful.

硕士topic一大堆,博士topic比较难找.

发帖数: 3060 | 14 I don't think under load dump you are still required to operate the DCDC,
The wide input range may be applied to, say DCDC from supercapacitor banks
to high voltage bus in hybrid vehicles.

发帖数: 69 | 15 NSM has a switching controller (maybe regulator) with something like 7 to
100V DC input range, useful for many on-road or off-road automotive
applications where you can save (or simplify) the required load dump
protection circuit.
DC/DC and power management are always useful and challenging, when other hot
fields come and go. 加油! |

像我们这样用PWM IC作power supply最终死路一条，看太多的layoff了

现在功率密度比较高的一个变换器大概 1kw/in^3 大概60W 左右
我做了一个500w/in^3 的，大概500 W~1 kW的变换器左右，
虽然还没到极限，但是快了， |

老大在哪里高就呀
我也是搞电源的，大功率通讯电源模块 1U 2U这样，我们一个2U的模块做到58V150A,呵
呵 |

搞头的 |
