Application Field

The VS-SD303C16S15C is a 3-phase, 1600V, and 15A SCR that has multiple uses in various industries. With its low thermal statistics, it is one of the most powerful SCRs available. Versatile and efficient, this device can used for mains power factor correction, frequency changers, rectifiers, motor control, UPS, invertors, and AC regulators.

In terms of power ratings, its RMS high-speed reverse recovery and bus soft switching makes it suitable for high power factor correction and elimination of harmonics. This device is also ideal for other high power applications that require dynamic braking, high frequency rapid switching, cost effective, high reliability, and low cost.

Working Principle

The working principle of the VS-SD303C16S15C is based on the usage of a high speed switching thyristor or SCR unit. This device is able to control and regulate the current through its power circuit using an electric impulse applied to the gate terminal. When the gate receives an electric impulse, it in turn controls the main current flowing from the cathode to the anode. This allows for higher levels of power efficiency and accuracy.

The VS-SD303C16S15C SCR allows the controlled application of AC power to the load. This is possible because the SCR can be effectively triggered and commutated for controlling high power AC loads. It can be used in either linear or pulse width modulation (PWM) mode.

When used in linear mode, the voltage across the SCR is proportional to the load current. This allows for the transfer of power to the load with maximum efficiency and power factor.

Due to its fast recovery and low on-state voltage drop, the VS-SD303C16S15C can control both the current and voltage. It can be used to precisely control the load at any desired power level.
