Conventional SSR solutions use isolated gate drive power supply for the MOSFETs of each SSR in a multichannel SSR circuit sharing the same AC supply. For example, with a six-channel SSR circuit, the conventional solutions use six isolation elements as shown in Figure 2-3, to eliminate potential turn on of relays, when other relays connected in the same AC supply is turned on. The isolation can be realized using independent transformers or optocouplers or capacitive isolators or any other isolation methods. Use of individual isolated gate-drive circuits leads to increased system cost and more board space.
