Homemade passive adjustable constant voltage electronic load
Source: InternetPublisher:王达业 Keywords: Electronic load constant voltage source Updated: 2023/12/13
The working principle of the circuit is relatively simple. S1 in the figure is the load switch. Disconnecting S1 can disconnect the entire load. R3 is the input voltage adjustment, and V3 and R5 form a current limiting protection circuit. In actual design, V2 can be equipped with a heat sink with appropriate thermal resistance according to the required power.
