MOSFET Interlock Circuit for Energy Storage Short-Circuit Prevention

The interlock device applies preliminary anti-action by detecting the operational state of circuits before allowing new operations to commence. The interlock circuit generates interlock signals that prevent drive signals from being output to circuits that are already operating, thereby preventing short-circuits before they can occur. This is achieved through the interlock processing circuit that continuously monitors circuit states and blocks potentially harmful simultaneous operations.

The interlock device achieves multi-functionality by integrating multiple functions into a single unified circuit structure. The interlock processing circuit simultaneously performs state detection, interlock signal generation, and drive signal control for multiple circuits. This universal design allows the same interlock mechanism to protect multiple circuits without requiring separate interlock circuits for each, thereby reducing overall device complexity while maintaining high reliability.

The interlock device implements periodic action by monitoring circuit states at specific intervals rather than continuously. The interlock processing circuit checks operational states periodically through sampled signals, generating interlock signals only when necessary to prevent short-circuits. This periodic monitoring approach maintains safety by detecting circuit states at critical moments while significantly reducing energy consumption compared to continuous monitoring, as the monitoring circuit is activated only when state changes occur or at predetermined time intervals.
