- Noise Immunity: Excellent common-mode rejection ratio (CMRR) to prevent false triggering.
Application Scenarios:
- Gate drive isolation in ABB ACS and DCS drive families.
- Medium-voltage and high-power inverter applications.
- Industrial motor control and variable frequency drives.
Material Composition & Structural Characteristics:
- Core Material: High-permeability ferrite core for efficient pulse transmission.
- Enclosure: Compact, flame-retardant plastic housing.
- Terminals: PCB-mounted pins for direct soldering or socket mounting.
Working Principle:
The TPPB-02 utilizes magnetic coupling to transfer gate drive pulses from the primary (control) side to the secondary (power) side. The transformer passes the fast-switching edges of the pulse while blocking any DC component or high-voltage transients, providing complete galvanic isolation.
Installation Requirements:
- Solder or plug the module into the designated gate drive board location.
- Maintain adequate creepage and clearance distances on the PCB.
- Ensure proper routing of secondary-side wiring to minimize parasitic inductance.
Usage Precautions:
- Do not exceed the maximum pulse width or duty cycle specified in the datasheet to prevent core saturation.
- Handle with ESD precautions to protect internal windings.
