Solid state relay videos

A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. Packaged solid-state relays use power semiconductor devices such as thyristors and transistors.

Here are some SSR videos worth to watch:

    TIDA-050059
    Overcurrent and overtemperature protection for solid-state relays reference design
    https://www.ti.com/tool/TIDA-050059?HQS=null-null-hv-hvisolation_tida050059-asset-rd-electronicdesign_psfi_isolation_l2-wwe_awr&DCM=yes&dclid=CJyF1Pfr6oEDFQ9IHgId6sYPPA

    This reference design shows how to achieve overcurrent and overtemperature protection for a solid-state relay. The reference design features the TPSI3050-Q1 5-kVRMS reinforced isolated switch driver. TPSI3050-Q1 device integrates a laminate transformer to achieve isolation while transferring signal and power to the secondary side. This removes the need for any isolated bias supply. In addition, the TPSI3050-Q1 device can supply power to external circuitry located on the high voltage (HV) side. This reference design can support up to 500-VDC or 350-VAC switching with a max of 4-A loading conditions.

    Features
    No isolated secondary supply required
    3-kVRMS reinforced isolation
    500-VDC/350-VRMS load with 4-A max
    Two-level overcurrent protection
    >2-A 100-ms load disconnect delay
    >5-A immediate load disconnect
    Two-level overtemperature protection
    >60°C LED visual warning
    >90°C immediate load disconnect
