FLYBACK VS. LLC POWER SUPPLIES: HIGH-VOLTAGE CONVERTERS SERIES
Isolated gate drivers are key parts of power converters, and require isolated power supplies to provide the gate driving voltage without breaking the isolation barrier. One of the most frequently used topologies for these applications is the flyback converter. However, increased leakage inductance caused by minimizing the interwinding capacitance loosens the coupling between the primary and second...

New applications requiring better efficiency and higher power density are increasing demand for components with bidirectional operation, able to transmit power to and from the grid without affecting efficiency. Totem-pole topology offers several advantages over traditional bridged power factor correction (PFC) because it requires fewer semiconductor components. As such, it has become an increasing...
GATE DRIVING FOR HIGH-VOLTAGE CONVERTERS: UNDERSTANDING ISOLATED GATE DRIVERS
Gate drivers control the commutation of power switches, such as field-effect transistors, and are used in many high-voltage applications, including solar inverters, uninterruptible power supplies, charging stations, and on-board chargers. Isolating the power path from the sensitive control signals protects the user and prevents malfunctions. Electrical isolation barriers can be implemented in thre...
GATE DRIVING FOR HIGH-VOLTAGE CONVERTERS: GATE DRIVER PROTECTIONS – COMMON MODE TRANSIENT IMMUNITY (CMTI)
Common-mode transient isolation (CMTI) protects the circuit by preventing high-frequency voltage components from coupling past the isolation barrier. Insufficient CMTI means high-power noise could be coupled across the isolated gate driver, generating a current loop and charge at the switch gate, leading to a failed CMTI test. Not meeting CMTI requirements can also cause serious circuit malfunctio...
