Allocation of personnel, resource and capital investment must create adequate returns on investment. The use of an outsourcing manufacturing model provides a method to improve corporate flexibility, time-to-market, agility and focus. However, the unique nature of power supply technology and manufacturing methods represent a risk to the successful adoption of an outsourcing model. The solutions to problems presented in adopting a contract manufacturing model offer opportunities for process improvements that ultimately improve competitiveness through cost reduction and reduced time to market.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

In this paper, experimental verification of the MCD concept is presented for the first time by using commercially available power MOSFETs operating as MCDs. Measurements of the reverse recovery currents and reverse recovery charges of these MCDs are obtained and compared with the body diodes of the MOSFETs. These measurements show that these MCDs can significantly reduce the reverse recovery current, storage charge and switching loss. Optimized MCD performances at 1.2 kV, 2.4 kV and 4.5 kV are also projected based on numerical simulations. Ideal performance of the MCD close to that predicted by device simulation should be obtained once an optimized MCD is developed.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

The main switches turn-on occurs naturally in ZCS, due to the operation in C-DCM. In addition, C-DCM also reduces the reverse recovery losses of the boost diodes. The use of auxiliary commutation circuits provides ZCS at the main switches turn-off. These circuits are activated only during the main switches commutations. By using the interleaved converters technique, the input current ripple is minimized. The control circuit of the converters has been implemented using a single erasable programmable logic device (EPLD) EPM7128SLC84-15 from Altera Corporation.
