Compact: Half-Bridge: Reinforced Isolated Gate Drive Reference Design
Description
This reference design is a half-bridge isolated gated driver used in driving power stages of UPS: inverters: server and telecom applications. This reference design is based on the UCC21520 reinforced insulated gate driver and is capable of driving MOSFETs and SiC-FETs. The design contains a built-in isolated push-pull auxiliary power supply for powering the output of the isolated gate driver. By bringing together the isolated gate driver and isolated power supply in a compact board with a form factor (!~30 mm × 35 mm): this reference design provides a fully tested robust half-bridge driver solution capable of withstanding >100 kV/μs common-mode transient immunity (CMTI).
Features
- Compact gate drive for driving power stages used in mid- and high-voltage power converters: single-phase and three-phase invertersHigh-driving current (4-A source and 6-A sink) suits driving MOSFET/ SiC-FET with currents up to 100 A and operating frequencies up to 2 MHz: which reduces switching losses significantlySupports 3250-VPK and 3000-VRMS basic isolationProvides very High CMTI of > 100 kV/μs for robust operation in noisy high dv/dt environmentIntegrated dead-time in gate driver improves reliability and avoids accidental shoot through of the power stage.Built-in compact: high-efficient isolated supply to power the output side of the gate driver
