Silicon Controlled Rectifiers (SCRs) are four-layer (PNPN) semiconductor devices that act as controlled switches for high-power applications. As key members of the thyristor family, SCR modules enable precise control of electrical power in industrial systems. Their ability to handle high voltages (>6000V) and currents (>5000A) makes them indispensable in power electronics, particularly for AC/DC conversion, motor speed control, and load management systems.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Single-phase SCR Module | Compact design with integrated snubber circuitry | Single-phase motor controllers, heating systems |
| Three-phase SCR Module | 6-pack configuration for 3-phase power control | Variable frequency drives, industrial furnaces |
| Reverse-Conducting SCR (RC-SCR) | Integrated freewheeling diode for inductive loads | Traction converters, welding equipment |
| Light-Triggered SCR (LTSCR) | Optical gate activation for high-noise environments | High-voltage DC transmission systems |
| SCR Power Stack Module | Multi-chip parallel configuration for extreme currents | Electrolysis plants, large motor soft starters |
Typical SCR module construction includes:
Advanced modules integrate temperature sensors and MOV-based overvoltage protection.
| Parameter | Typical Range | Importance |
|---|---|---|
| Rated Repetitive Peak Voltage (VRRM) | 600V - 6500V | Determines maximum operating voltage |
| Rated Average On-state Current (ITAV) | 25A - 3000A | Defines continuous load capacity |
| Gate Trigger Current (IGT) | 50 A - 50mA | Affects control circuit design |
| dv/dt Capability | 10-500 V/ s | Indicates immunity to voltage spikes |
| Thermal Resistance (Rth) | 0.01-0.5 K/W | Impacts cooling requirements |
Primary industries utilizing SCR modules:
Case Study: 3 MW wind turbine converter using 1700V/1200A SCR modules achieves 98.5% conversion efficiency.
| Manufacturer | Representative Product | Key Features |
|---|---|---|
| ABB | 5SNA 2400K170300 | 1700V/2400A, press-pack design, 50kA short-circuit rating |
| ON Semiconductor | CM400HA-34H | 1600V/400A, hockey puck package, <2V forward voltage |
| Infineon | B25801-A1047 | 1200V/800A, integrated heat sink, RoHS compliant |
| Mitsubishi Electric | PM100CL1A-120 | 1200V/100A, low inductance package, 150 C operating temp |
