よくある質問

Q1:

What is Phase Control Thyristors?

リ: Phase Control Thyristors, also known as thyristors, are semiconductor power electronic devices that can adjust the voltage and current of input AC power by controlling their conduction angle.

第2四半期:

What are the characteristics of Phase Control Thyristors?

リ: Phase Control Thyristors have the characteristics of high voltage resistance, 大電流, low conduction impedance, and fast response and are widely used in various power control and regulation systems, such as dimmers, speed regulators, uninterruptible power supplies, 等.

Q3:

What is the working principle of Phase Control Thyristors?

リ: Phase Control Thyristors is to control its conduction angle by controlling the voltage of its gate, thereby adjusting the voltage and current of the input AC power. When the gate voltage is zero, the thyristor is in the cut-off state. When the gate voltage reaches a specific value, the thyristor begins to conduct, and the magnitude of its conduction angle depends on the amplitude and width of the gate voltage.
