EASYGEN-3200-5 Woodward speed control module

The EASYGEN-3200-5 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward EASYGEN-3200-5
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- EASYGEN-3200-5 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

For lower gate drivers, the 0.4 ohm impedance of the driver can keep the gate of the power MOSFET below the threshold level to ensure that

no through current occurs during high dV/dT phase node transitions. The internal diode charging bootstrap capacitor enables the device to use

N-channel MOSFETs in a half bridge configuration. The tri state pulse width modulation (PWM) input provided by TPS28225 is compatible with all multi-phase controllers such

as TITPS40091. The power-off mode can protect the load from the influence of reverse output voltage.

The TPS28225 MOSFET driver is now in mass production and can be ordered through TI and its authorized distributors. This device is available in two packaging versions

: a low-cost 8-pin SOICDFN package and a heat dissipation enhanced 3mm x 3mm 8-pin DFN package.

IR2117 is a gate driver integrated circuit designed by IR Corporation in the United States specifically for driving individual MOSFETs or IGBTs. IR2117 is a gate driver designed by IR

Corporation in the United States specifically for driving single MOSFETs or IGBTs. It uses high-voltage integrated circuit technology and latch free CMOS technology, and adopts a

dual in-line package, which can be used in systems with working bus voltages up to 600V. Its input is compatible with standard CMOS levels, and its output driving characteristics can meet the

design requirements of high current driven output stages with the shortest cross conduction time. The application of its floating channel and bootstrap technology allows it to be directly

used to drive an N-channel MOSFET or IGBT that operates on the high or low side with a bus voltage of up to 600V.

2. Internal structure and working principle

The internal structure and working principle diagram of IR2117 are shown in Figure 2. It integrates nine unit circuits internally, including a Schmitt trigger, a pulse gain circuit, two undervoltage

detection and protection circuits, a level shift network, a NAND gate, a complementary power amplifier output stage composed of two MOSFETs, an RS trigger, and a pulse filter.

During normal operation, if the logic power supply and output power supply of IR2127 are not under voltage, the signal from the user controlled pulse forming unit is first shaped by a Schmitt trigger,

then amplified by a pulse gain loop, and level shifted and matched by a level shift network. After being triggered by an RS trigger, it is output by a complementary push-pull output stage to drive an external MOSFET or

IGBT. Once either the input logic power supply or the output amplifier stage floating power supply experiences undervoltage, one of the output signals

will be blocked, causing the output drive pulse to become low level.
