1.Selection of grid-driven Optocoupler for Photovoltaic Igbt?

TD3120R,TLP57xx series couplers can be considered for the type selection of PV grid drive optocouplers. This series of products has the same package and rich product series, the output peak current is 1A to 4A, the input threshold current is 2MA to 4MA, the minimum operating voltage is 10V to 15V. In addition, the series of products also have rail-to-rail output and ultra-thin packaging and other features. It can be used forgrid drive in applications such as PV inverter power regulator.

2.How does the IGBT drive optocoupler work?

IGBT -LRB-Insulated Gate Bipolar Transistor)-driven optocoupler is a device that uses light as a medium to transmit electrical signaIt. It is usually enclosed in a tube housing by a light emitter and a light receiver. Optocoupler has a good isolation effect on the input and output electrical signals, so it is widely used in various circuits. The IGBT driver modules available in the market include Fuji EXB840,841, Mitsubishi M57962L, TD3120R, TD3150, HP HCPL316J, 3120, etc. . These modules have the functions of over-current soft-switching, high-speed optocoupler isolation, under-voltage locking and fault signal output. Because this kind of module has the advantages of perfect protection function, no debugging and high reliability, the application of this kind of module to drive IGBT can shorten the product development cycle and improve the product reliability.

3.What are the characteristics and applications of TD3120?

Application field: isolated IGBT / power MOSFET gate driver, industrial inverter, solar inverter, household atomizer, microwave oven, induction cooker, printer, projector, laptop computer, remote monitoring robot.

4.How to be applied in the energy storage inverter?

One of the key features of the TD3120 gate-driven photocoupler is its ability to provide high peak output current for charging or discharging IGBT rapidly preventing switching loss. The gate drive photocoupler has an output current range from 0.4A to 5A and can be used to directly drive the small IGBT. For the higher grade IGBT, the discrete PNP / NPN duplex analysis level is usually used. By changing the bufer level to MOSFET, it enables the door to maximize the scalability and power conversion capability of the drive design.

5.TLP250 And TD3120 drive design difference?

Early and low power frequency converter machine, often using TLP250, A3120 (HCPL3120) drive IC, simple internal circuit, excluding IGBT protection circuit; later, a large number of PC923, PC 9929 combination drive circuit, often the three arm IGBT is driven by PC923, while the lower three arm IGBT is driven by PC929. PC929 contains IGBT detection and protection circuit; A316J is also used in a large number of models. Three kinds of drive IC pin function, small power models available TLP250 directly for the other two HCNW3120 and HCPL3120, in most cases TLP350, HCNW3120 is interchangeable, although their individual parameters and internal circuit differences, such as TPL250 current output capacity is low, but in the frequency converter power models, drive IC often have rear amplifier (expanding flow push pull circuit), to drive IC current output capacity is not too picky. TD3120 Driver chip TD3120R Door drive photoelectric couplers contain GaAsP LED, which are optically coupled to an integrated circuit with power level output. These photoelectric couplers are very suitable for driving motors to control the power IGBT and MOSFET in frequency conversion applications. The high working voltage range of the output level provides the driving voltage required for the gating device. TLP250 Driver chip TLP250 Contains a GaAlAs light-emitting diode and an integrated light detector with an 8-legged double-column package structure. Suitable for the IGBT or power MOSFET gate drive circuit.
