ED-WP-CB
Firstack ED-WP-CB digital gate driver core, 4 W / 110 A, 1700 V, for multi-parallel 3-level NPC and ANPC converters.
The ED-WP-CB is a Firstack high-performance digital gate driver core developed for NPC I-type and ANPC 3-level systems, with a 4 W drive power, a 110 A peak output current and a 1700 V maximum breakdown voltage. It is built for multi-parallel 3-level converters, which are widely used in photovoltaic, wind and energy-storage systems because they reduce switching loss and improve power quality at a high DC bus. The digital core integrates the controller, the isolation and the protection, and its protection set includes short-circuit detection, undervoltage lockout, soft shutdown, fault sequencing and NTC detection, so the converter can manage a fault in an orderly way across the parallel modules. The multi-parallel 3-level topology places special demands on the driver because the commutation circuit is large and the stray inductance is high, which is why the driver sequences the fault and uses soft shutdown. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm the topology and set the gate resistors and protection for their converter. Availability is confirmed per project; BeiLuo reserves supply against your forecast.
FAE Professional Review
The ED-WP-CB is the driver core for 3-level NPC and ANPC converters at 1700 V, where the large commutation circuit makes fault sequencing essential. It handles multi-parallel modules cleanly and detects the module temperature through NTC. Confirm the topology and set the gate resistors before committing.

Frequently Asked Questions
What converters suit the ED-WP-CB?
It suits 3-level NPC and ANPC converters at 1700 V, such as photovoltaic and wind inverters and energy-storage converters, especially multi-parallel designs where several modules share the current.
For a 2-level converter, the 2FHC cores are simpler.
Why is fault sequencing important in a 3-level converter?
A 3-level converter uses several modules in series and often in parallel, so a fault must be handled in the right order to avoid overstressing the remaining devices. Fault sequencing turns the modules off in a defined sequence with soft shutdown, which protects them all.
Our FAE team can explain the sequencing.
Is lead time longer for this core?
Stock status for the ED-WP-CB is confirmed per request, and specialized cores can be allocation-managed. BeiLuo sources through Firstack's authorized channel and reserves supply against your plan.
