This voltage regulator, though using older components, features a simple and robust circuit design described as "manual work of the late 60s or early 70s". It incorporates a bridge rectifier for current limiting and is suitable for AC operation. Circuit Function: The regulator manages battery charging using a simple DC regulator, not designed for direct AC operation. Circuit Diagram: The provided schematic shows: Input: AC from the generator and a "Sense" line for voltage feedback. Rectification & Regulation: A bridge rectifier (using diodes like 1N5408 and 1N4007) converts AC to DC. A resistor network (1K, 500R, 750R, 5K) along with a component labeled 67151 (likely a transistor or SCR for regulation) and RV4 (a potentiometer for adjustment), likely form the core of the voltage regulation.

High-frequency mixed pressure board is a type of circuit board that combines the high-frequency circuit transmission performance with the complex wiring capability of multi-layer boards. Its main functions are as follows: - High-frequency signal transmission: It can reduce signal loss, distortion and interference during high-frequency transmission, ensuring signal integrity. It is commonly used in high-frequency fields such as 5G communication, radar and satellite communication. - Multi-layer mixed wiring: Through a multi-layer structure, it can achieve complex circuit wiring, meeting the design requirements of high-density and multi-functional circuits, and integrating different functional modules. - Impedance control: It can precisely control the characteristic impedance, ensuring signal transmission quality and avoiding problems such as signal reflection caused by impedance mismatch. - Heat dissipation and mechanical support: Some materials have good heat dissipation properties, and the multi-layer structure can also provide mechanical support for the circuit, ensuring the stable operation of the equipment. #Rogers4350B and #FR4 mixed pressing

Protecting the internal electrical components while satisfying the highest technical and aesthetic requirements. EMS polyamides are preferred materials for frames, housings and display windows. In miniaturised electronic components such as LEDs or connectors, EMS polyamides ensure highest precision and are also resistant to heat and soldering. Miniaturisation and faster switching operations place increasingly high demands on mechanical and thermal requirements for electricity supply components. Replacement of metal is a major topic where above all, impact strength and dimensional accuracy play an important role. DM Joe Clinch or Joe Read with your questions

A 5-pin relay is a type of electromechanical switch that uses an electromagnetic coil to control the connection between circuits. It is commonly used in automotive and some industrial electrical systems to control high-current loads with a low-current switch. Here’s a breakdown of the pins on a standard 5-pin relay: Pin Configuration (SPDT – Single Pole Double Throw) Pin 85 → Coil Ground (negative) Pin 86 → Coil Positive (trigger, from switch/ignition/etc.) Pin 30 → Common (power input, usually from battery/fuse) Pin 87 → Normally Open (NO) output (gets power when relay is energized) Pin 87a → Normally Closed (NC) output (has power when relay is NOT energized) Working Principle When no power is applied to the coil (85 & 86), Pin 30 is connected to 87a. When power is applied to the coil, the internal switch shifts, and Pin 30 connects to 87.

MOSFET Self Turn-On Phenomenon : One of the hidden challenges in power electronics design is the self turn-on of MOSFETs. It occurs when the device unintentionally switches ON due to Miller capacitance (Cgd) and voltage transients across drain and gate. This unwanted behavior can lead to : ⚡ Increased switching losses 🔥 Higher device stress & heating 💥 Risk of shoot-through in half-bridge/phase-leg topologies 👉 To mitigate self turn-on : Use gate resistors or negative gate drive Select MOSFETs with low Crss (Cgd) Apply proper layout techniques to reduce dV/dt Gate driver ICs with Miller clamp are highly effective Understanding and controlling this phenomenon is key to designing robust, efficient, and reliable power electronics systems.

Constant Current Limiting Circuits In any power supply it is essential design practice to have a scheme for limiting the output current should a fault occur and excessive current be drawn. Without this, not only could the item being powered suffer additional damage, but the power supply could also fail. Introducing a current limiter is essential. Fortunately this is very easy to achieve. For linear regulators there are several circuits that can be used for constant current limiting for power supply protection, but one of the simplest circuits uses just three additional electronic components: two diodes and a resistor. This assumes that the series regulator transistor is already present. The circuit for the power supply current limiter uses a sense resistor placed in series with the emitter of the output pass transistor. Two diodes placed between the output of the circuit and the base of the pass transistor provide the current limiting action. When the circuit is operating within its normal operating range a small voltage exists across the series resistor. This voltage plus the base emitter voltage of the transistor is less than the two diode junction drops needed to turn on the two diodes to allow them to conduct current. However as the current increases so does the voltage across the resistor. Discover more: https://lnkd.in/gdY326h #powersupplies #currentlimiter #circuitdesign #linearregulator
