Active Diode Module
|
|
 |
Product Part Number : ADM012-6 The Active Diode Module is a new patented technology (US Pat. 6,134,131) for high efficiency output rectification. With an external MOSFET it replaces output Schottky diodes at the output of most switching power supplies. Actually the Active Diode Module is a special type of synchronous driver for low loss MOSFETs. Current through the MOSFET is sensed by an internal current transformer and the MOSFET is turned on according to the current flow. Current sensing energy is regenerated to an external DC voltage source, which is conveniently the output of the power supply. The external voltage source for energy recovery is isolated from the MOSFET by the current transformer, this makes the Active Diode Module applicable to output rectifiers for all types of power circuit topologies like flyback, forward, resonant, etc. |

EMI Cancellation IC
|
|
 |
Product Part Number : WT6001 This new EMI cancellation technology relief power supply products from bulky passive filters. It employs a new technology which greatly reduces common mode noise typically by 20db and it works in power supplies of all power levels. The technology can be easily understood as a Y-cap booster circuit that provides a very low impedance path to bypass noise current between any two nodes in a circuit within the conducted EMI frequency spectrum. This IC produces an effective cancellation signal to reduce common mode current. The IC deals with low power noise current only its application is not limited by converter power level. Built-in protection circuits allow operation against hi-pot tests and high voltage applications. It is intended to reduce conventional passive filter requirement which introduce considerable losses and size to switching power converters. Significant reduction in size, cost and loss of EMI components makes your product more compact and highly efficient to meet nowadays tight requirements. |
