PURPOSE:To reduce the distortion at the start of trasmission by fixing the potential of both terminals of a primary winding of a pulse transformer forcibly to a power supply voltage at non-transmission so as not to flow a current to the primary winding at non-transmission. CONSTITUTION:When ...
• Signal pulse transformerAs the title suggests, signal pulse transformers are used for carrying control signals and the power levels are not at all high. The power levels are typically quite low and the focus of these transformers is on providing a good low level pulse to the circuit that...
A switch-driving circuit suitable for driving a full-controlled power switch combination is disclosed. The switch-driving circuit includes a first pulse-width modulator, a high-voltage isolation pulse transformer module and a plurality o... HJ Gan,WL Fu,M Wang,... 被引量: 0发表: 2014年 ...
Design and Simulation of Gate Driver Circuit Using Pulse Transformer Pulse transformer is always used to be the isolator between gate driver and power MOSFET. There are many topologies about the peripheral circuit. This paper proposes a new topology circuit that uses pulse transformer to transfer dr...
There is a circuit shown in the UCC27714 datasheet, but as someone on E2E pointed out, it has an issue. Another option would be to use a dual channel isolated driver, which can handle a lot of voltage transients. Lastly, if you are ...
driver system in electric vehicles. The typical input voltage is 15V with 100KHz switching frequency, winding (6-8) provides +15V output with full-bridge rectifier for IGBT switch on, and winding (5-7) provides -7.5V with half-bridge rectifier for switch off. See the application circuit ...

When you are a Hackaday writer with some oscilloscope bandwidths to measure, you needa picosecond avalanche pulse generator, and you need one fast. Fortunately they’re a very simple circuit with only one 2N3904 transistor, but the snag is they need a high voltage power supply well over 100...
FIG. 4is a schematic diagram of the gate driver including the pulse transformer and Schmitt trigger circuit connected to the secondary side of the pulse transformer. FIG. 5is a schematic diagram of the power supplies for the motor controller. ...
