In inverter circuits, a **watchdog timer** serves as a safety mechanism to monitor and ensure that the system operates correctly. If the inverter system gets stuck or stops functioning properly, the watchdog timer resets it to prevent malfunction or damage. Here's how it works:
1. **Monitoring Operation**: The watchdog timer continuously monitors the inverter's operation by expecting periodic "kick" signals or reset pulses from the system's control circuit.
2. **Detecting Failures**: If the control circuit fails to send these reset signals (e.g., due to a software malfunction or a fault in the system), the watchdog timer assumes the system is not functioning properly.
3. **Triggering a Reset**: Once it detects that no reset signal is received within the expected time frame, the watchdog timer triggers a reset or reboots the system, restoring the inverter to a known good state.
This function is essential in maintaining the stability and reliability of inverter circuits, especially in critical applications like renewable energy systems or industrial power supplies, where continuous and uninterrupted operation is important.
