Designed high power welding machine and charging station of the electric vehicle, the DMR95 ferrite material gives the full-bridge topological transformer extraordinary working properties under 50 kHz - 200 kHz with the power between 5 kW - 40 kW.
A type of Transformer with flat design, suitable of high density electronic devices.
Soft-Switching Resonant Inductor
With the increasing demands of the soft-switching power supply circuit, many producers are confronting the low homogeneity in mass production, which refers to the source of controlling signal which is generated by the leakage inductance of the transformer and stray capacitance of power MOSFET. To get rid of this problem, the common solution is to add the resonant inductance. Therefore the designer shall consider the choice of an inductor with properties of:
Application: switching power supply
Thank to the long history of development in moulded inductor, Crootem provides all series of SMT inductors with high power density, which are the most suitable for high power density module or POL (Point of load) power supply with VRM, VTM and other techniques.
Consultation and Engineering Services:
By introducing the cascaded H-Bridge multilevel inverter topology and an advanced algorithm on a digital signal processor (DSP), the UPS inverts DC current to 3-phase AC output. Together with the modular, hot-plugging, multi-mode, decentralized logic parallel connection, touch panel operation, this device is equipped with the latest technology. Comparing with the other inverter, the power loss and the high order harmonic of output are reduced by nearly 50%. With the small size, we have achieved even higher power density.
Crootem offers quick prototyping service, with very low cost. For more information, Contact our sales personals:
