A power supply unit is one of the most crucial components in an electronics system, as its operation can affect the entire system’s functionality. In the context of industrial functional safety, as in IEC 61508, power supplies are considered elements and supporting services to electrical/electronic/programmable electronic (E/E/PE) safety-related systems (SRS) as well as other subsystems.

Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, however, are prone to pathological drifts, such as temperature variations and mode-hopping, that can alter the output intensity. A popular approach to stabilize the output intensity is to first convert the photodiode current to voltage.

Inductor-inductor-capacitor (LLC) resonant converters have a couple of appealing characteristics for applications requiring an isolated DC/DC converter such as minimal switching losses, no reverse recovery when operating below the resonant frequency and the ability to tolerate large leakage inductance within the transformer. The challengeA primary challenge when designing an LLC converter with a wide operating range is the behavior of the gain curve with respect to equivalent load resistance.

In April 2012, EDN published a circuit by John Fattaruso that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET. The pinch-off voltage (Vp) is measured by inserting a very large resistance between the source and the ground. The drain-source saturation current (IDSS) is measured by inserting a small resistance between the source and the ground.

For those who may not know, Mike Engelhardt is the author ofLTspice, which was originally produced by Linear Technology and eventually bought by Analog Devices Inc. LTspice was not Engelhardt’s first rodeo with writing simulators; he got his start in the 1970s simulating particle collisions at a physical lab and later writing a simulator for a scanning electron microscope, a program that ran on a cluster of Sun workstations at the time.
