In particular, isolation circuits are used to transfer signals or power completely from one circuit to another while achieving electrical isolation even though there is a different position or potential difference between the two circuits. Primary and secondary circuits are two important parts of an isolation circuit, the primary being typically the input, which receives a source of signal or power. In an isolated circuit, the primary circuit is typically physically isolated from the external circuit by an isolation barrier (e.g., transformer, optocoupler, etc.) to prevent the transmission of direct current or signals, the primary being responsible for receiving and transmitting energy. The secondary side circuit is typically an output that converts the signal or power delivered from the primary side to a final output signal or power. Communication between the secondary and primary circuits is through an isolation barrier (e.g., transformer, optocoupler, etc.) such that the two circuits remain electrically isolated. In an isolated circuit, the transmission between the primary and secondary sides is through a physically isolated medium. Such isolation may be achieved using different techniques, such as transformers, optocouplers (optocouplers) or magnetic couplers. The isolation techniques can prevent the problems of electric noise, position difference, potential difference and the like from spreading between the primary side and the secondary side, and realize effective isolation and protection.
