Analysis of bidirectional switch solutions based on different power devices

The numerous limitations of Electro Mechanical Relays (EMRs) for implementing Single-Pole, Single-Throw (SPST) Bi-Directional Switches (BDS) lead to new developments based on power semiconductor devices. This work gives an insight into the design and operation of BDSs based on the combination of unidirectional voltage blocking and bidirectional current conduction power devices, which aim to substitute EMRs in home appliances. The developed BDSs are fully characterized.
