Avec le développement rapide de la technologie de l’électronique de puissance, les appareils électroniques de puissance sont de plus en plus utilisés dans divers domaines. Parmi eux, un thyristor commandé en phase, un appareil électronique de puissance avancé, has broad application prospects and crucial practical value. This article will give you an deadly understanding of the characteristics, working principles, advantages and limitations of phase-controlled thyristors and performance evaluation.

Introduction to phase-controlled thyristors

Phase Control Thyristor is a semiconductor device with self-turnoff capability that controls voltage and current by controlling the phase angle. It has the characteristics of high efficiency, economize on energy, fast response, and high reliability. It is extensively used in reactive power compensation, power factor correction, motor control and other fields of power systems.

Working principle of phase-controlled thyristor

The working principle of the phase-controlled thyristor is based on a semi-controlled rectifier circuit. The output voltage and current are indicated by controlling the trigger signal's phase angle. When the phase angle of the trigger signal is less than 90 degrés, the thyristor is turned on, and the output voltage and current increase; when the phase angle of the trigger signal is greater than 90 degrés, the thyristor is turned off, and the output voltage and recent decrease. By adjusting the phase angle of the trigger signal, precise control of the output voltage and current can be achieved.

Comparison between phase-controlled thyristors and ordinary thyristors

Compared with ordinary thyristors, phase-controlled thyristors have the following advantages and limitations:

Avantage:

1. Self-shutoff capability: Phase-controlled thyristors have self-shutdown ability and can be turned off without external signals, simplifying the design of the control circuit.

2. Fast response: Phase-controlled thyristors have fast switching speeds and can adapt to the needs of high-frequency switching applications.

3. Energy-saving and efficient: By accurately regulating output voltage and current, phase-controlled thyristors can reduce energy loss and improve system efficiency.

4. Haute fiabilité: The phase-controlled thyristor has a simple structure, stable operation, and high reliability.

Limitation:

1. Trigger conduction requires a certain signal amplitude and leading edge steepness, placing higher trigger circuit requirements.

2. The ability to withstand voltage and current is limited and requires appropriate thermal design and structural optimization.

Performance evaluation of phase-controlled thyristors

1. Rated voltage and current: Rated voltage and current are essential parameters of the phase-controlled thyristor, representing the maximum voltage and current value it can withstand.

2. Switching speed: Switching speed reflects the response speed and ability of the phase-controlled thyristor and is an important indicator that needs to be considered in high-frequency applications.

3. Conduction loss and switching loss: Conduction loss and switching loss are the energy losses of phase-controlled thyristors during the conduction and switching processes. They are critical indicators for evaluating their energy efficiency.

4. Thermal performance: The thermal performance of a phase-controlled thyristor includes thermal resistance, junction temperature and other parameters, reflecting its working ability and stability in high-temperature environments.
