October 1, 2009[Ideas For Design] Control Current And Voltage Precisely For Regulators, Oscillators, And Amps
THE CURRENT REGULATOR IN Figure 1 boasts a very high current stability of around 1.7% within a temperature range that spans -40°C to 125°C. It can be used in precise current and voltage regulators, oscillators, and amplifiers. For its operation, the device utilizes a unique composition of thermal coefficients of bipolar transistors and Schottky diodes, which efficiently compensate for each ...
March 1, 2007[Design View / Design Solution] The Right Calculations Add Up To The Ideal Power Current Transformer
Current transformers measure current or transfer energy from one circuit to another, so their design requires calculations different from their voltage transformer cousins. The reason for the difference is that current transformer magnetizing current is the load current itself, unlike voltage transformers, where magnetizing current is "separated" from the load current and has a value that's a small fraction of the total current at full load. We want to supply the load with...
September 28, 2006[Ideas For Design] Cascode Configuration Removes Miller Effect, Boosts PFC Performance
The power factor corrector (PFC) front end of an off-line power supply is subject to the operating frequency limitation caused by the Miller Effect of its associated power MOSFET. This effect is a property of any transistor configuration with a common source (MOSFET) or common emitter (bipolar transistor) configuration. Most PFCs employ a boost converter based on a configuration with a common source MOSFET or common emitter power bipolar transistor. ...
