Solid State Relay Circuits

2 Lead Solid State Breaker Resets Itself: 03/30/95 EDN-Design Ideas / Simple dc circuit breaker can protect a power supply from the ever-present screwdriver or even isolate a satellites dual power system from a short circuit in one subsystem

AC Switching With TRIAC From TTL:

RF Front End for Triple Conversion GPS Receiver:

SCR Phase Control yields Solid State Switch: 03/15/01 EDN-Design Ideas / PDF contains multiple circuits - scroll to find the one of interest / SCRs (silicon-controlled rectifiers) / PDF contains multiple circuits - scroll to find the one of interest, or thyristors, have higher current and voltage ratings, lower conduction losses, and more robustness than triacs. For these reasons, SCRs are better suited to high-power applications. This is high power dimmer circuit for115V AC.

Solid State Relay: 

Solid State Relay Saves Battery's Life: 09/01/94 EDN-Design Ideas

Solid-State Relay Features Load Indicator: 08/09/04  Electronic Design - Design Briefs / Several years ago, I designed a remote energy-control system that split a building into sections and wired the overhead space heaters into "zones." As space was an issue and OAC5s (optically isolated output modules) were way too big, each)

Solid State Switch for DC Operated Gadgets:

Solid-State Circuit Converts Temperature To Voltage: 10/30/00 Electronic Design - Ideas for Design / This circuit is a solid-state thermometer suitable for measuring temperatures from −40°C to 125°C (Fig. 1). By adjusting RZERO and RSCALE.

Solid-State Multiplexers Reduce Half-Bridge Error: 01/24/00 Electronic Design - Ideas for Design / The half-bridge configuration is handy when using nonlinear sensors, such as thermistors, since it can partially compensate for the sensor's nonlinearity.

Solid-state Switch For DC-Operated Gadgets:

Switch Intelligently Controls Current: 03/30/00 EDN-Design Ideas / This circuit can intelligently control ac or dc current when connected in series with a load

Transformer Driver Controls Bidirectional Switch: 07/17/97 EDN-Design Ideas / You can use a transformer-driver IC to simply control a MOSFET on/off switch
