U0133-22 electrical component consists of two conductors placed close to each other with a non-conductive insulating dielectric layer in between, forming a capacitor. When voltage is applied across the two plates of the capacitor, it stores charge. The capacitance value is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the Farad (F). In circuit diagrams, the letter C is commonly used to represent capacitive elements; capacitors are components that store electric charge and electrical energy (electric potential energy). One conductor is surrounded by another conductor, or a conductor system where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

U0133-22 electrical component structure

Solid-state relays consist of three parts: input circuit, isolation, and output circuit. Depending on the input voltage category, input circuits can be divided into DC input, AC input, and AC/DC input types. Some input control circuits also feature compatibility with TTL/CMOS, positive/negative logic control, and inversion functions, allowing easy connection to TTL and MOS logic circuits. For control signals with fixed control voltage, resistive input circuits are used. The isolation and coupling methods between the input and output circuits of solid-state relays include optocoupling and transformer coupling: optocoupling typically uses photodiode-phototransistor, photodiode-triac optocouplers, or photovoltaic cells to achieve isolated control between the control side and the load side; high-frequency transformer coupling utilizes self-excited high-frequency signals generated by the input control signal, coupled to the secondary side, then demodulated, rectified, and processed by logic circuits to form drive signals. The power switch of the solid-state relay is directly connected to the power supply and load terminals to switch the load power on and off. Mainly used components include high-power bipolar transistors, SCRs, triacs, power MOSFETs, and IGBTs. The output circuit of solid-state relays can also be divided into DC output, AC output, and AC/DC output forms. Based on load type, they can be classified into DC solid-state relays and AC solid-state relays. For DC output, bipolar devices or power MOSFETs can be used; for AC output, two SCRs or one triac are typically used. AC solid-state relays can be further divided into single-phase AC solid-state relays and three-phase AC solid-state relays. AC solid-state relays can be classified into random-turn-on AC solid-state relays and zero-crossing AC solid-state relays based on the timing of conduction and turn-off.

U0133-22 electrical component principle

Mainly consists of LC circuits composed of capacitors and inductors, producing free oscillation through the mutual conversion of electric field energy and magnetic field energy. To sustain oscillation, an amplifier circuit with positive feedback is required. LC oscillators are further divided into transformer-coupled and three-point oscillators. Many applications use quartz crystal oscillators, and there are also LC oscillators composed of integrated operational amplifiers. Since component parameters cannot be perfectly identical, the states of the two transistors change at the moment of power-up. This change becomes increasingly intense due to positive feedback, leading to a quasi-stable state. During the quasi-stable period, the other transistor gradually charges via the capacitor and then conducts or cuts off, causing the state to flip to another quasi-stable state. This cycle repeats to form oscillation.

U0133-22 electrical component characteristics

The most important characteristic of a diode is its unidirectional conductivity. In a circuit, current can only flow into the anode and out of the cathode of the diode. 1. Forward characteristics: In electronic circuits, when the anode of the diode is connected to a high potential and the cathode to a low potential, the diode conducts. This connection method is called forward bias. It must be noted that when the forward voltage applied across the diode is very small, the diode still does not conduct, and the forward current flowing through it is very weak. Only when the forward voltage reaches a certain value can the diode truly conduct. After conduction, the voltage across the diode remains basically constant, known as the "forward voltage drop" of the diode. 6. Reverse characteristics: In electronic circuits, when the anode of the diode is connected to a low potential and the cathode to a high potential, almost no current flows through the diode, and the diode is in a cut-off state. This connection method is called reverse bias. When the diode is reverse-biased, a weak reverse current, known as leakage current, still flows through it. When the reverse voltage across the diode increases to a certain value, the reverse current increases sharply, and the diode loses its unidirectional conductivity. This state is called diode breakdown. The injection current of a laser diode must exceed the critical current density to satisfy the population inversion condition and emit laser light. The critical current density is related to the junction temperature and indirectly affects efficiency. During high-temperature operation, the critical current increases, efficiency decreases, and components may even be damaged.
