A dc-dc converter with integrated Magnetics and sensor and ZVS, ZCS circuit topology in one package to reduce the interconnects and the losses is proposed. The custom made three dimensional magnetic design will allow us to increase the switching frequency to >500kHz, while maintaining >92% efficiency at 12V output. The power devices and magnetic will be utilizing the high temperature common package with Direct Bond Copper, substrate for better heat transfer. The power converter will have integrated diagnostics and operation status reporting. The base plate will be integrated with the cooling fins to optimize the heat rejection. The proposed design is cost effective for low volume production and it is designed for dual use of DOD and heavy duty hybrid commercial vehicles and telecom. US Hybrid similar design dc-dc converts has passed the NEBS, telecommunications qualification, which includes the EMI/EMC, shock, vibration and drop test as well as thermal cycling. A high bandwidth control loop to provide fast transient with ramp compensated current regulated, phase shift ZVS converter with current doubler output inductors to minimize the stored energy on the unit input and out to enhance the transient response is considered.

US Hybrid proposes to combine 6 of it's currently commercially available FCe80 units upgraded to provide the necessary 500kW net electrical power. A redesign of the existing balance of plant to reduce weight and volume shall be performed, along with the necessary changes for thermal management given sea water cooling. The system shall have a DC-DC converter that will be utilized to maintain optimum voltage on the DC bus for components being supplied. Each of the 6 cell stacks utilized shall be in parallel allowing maintenance on individual systems without the need to disengage the remaining units.
