Jectronic PD-200X Double-Pulse Test Platform and Its Three Key Features

Jiechuang Instruments PD-200X

dual-pulse dynamic testing platform and three key features

The PD-200X dual-pulse dynamic testing platform developed and produced by Lygao Jiechuang Instruments offers high cost-performance, high stability and versatility, and features modular intelligent design

offers excellent instrument compatibility with probes, high redundancy safety ensures the safety of high-voltage and high-current testing devices and personnel, making this system currently the most cost-effective

dual-pulse testing system, especially suitable for universities, research institutes, and startup semiconductor companies

Through the PD-200X dynamic testing platform, the performance and reliability of IGBT/MOSET devices can be evaluated, and the driver circuits and thermal design

improves system efficiency and reliability. The dual-pulse testing method used on the platform is widely used in fields such as frequency converters, electric vehicles, and renewable energy power generation

1. System framework

The PD-200X system mainly consists of a high-performance oscilloscope, high-performance voltage and current probes, high-voltage power supply, optional inductor loads, power module mounting consoles, and programmable control software

tooling, fixtures, and other components. This system integrates the main testing equipment into a visual safety protection box, greatly improving the safety of personnel and equipment

integrates the program control module and PC host computer software to achieve intelligent operation control. As shown in the figure below

2. Hardware device configuration

Basic configuration:

1. Pulse generator

supports single pulse, dual pulse, adjustable 0.5~200μS, optical fiber and BNC outputs selectable, and safety control via host computer software

2. High-voltage power supply

provides the DC voltage required for testing, with a maximum operating voltage of up to 1200V, expandable to 1700V, and integrates a charge-discharge circuit

3. High-performance SiC digital drivers

gate voltage manually adjustable in six levels, -5V~+18V; Compatible with almost all brands of optical isolation probe interfaces on the market, such as Tektek, PMK, Zhiyong, etc

supports differential probes of all brands

4. Adjustable load inductors AirC100 series

independently designed hollow inductors with high linearity, easy connection with taps, and five manual adjustable inductance levels: 10uH, 20uH, 50uH, 100uH, and 200uH

5. Safety protective box

360° visual explosion-proof box, integrated system equipment to ensure safety protection for both equipment and personnel, newly upgraded intelligent safety alarms and voltage reduction triggers

Optional equipment:

6. High-definition digital oscilloscope

This system is compatible with all brands of oscilloscopes on the market. The high-end version can optionally include the IWATSU Japan Iwasaki DS-8000 series 12-bit HD oscilloscope

7. Signal acquisition probe

There are mainly four types of front-end acquisition probes: high-CMRR optical isolation probes measure Vgs, high-voltage differential probes measure Vds, and high-frequency inductive resistors can be paired with Roche coils to measure Id

High-end configuration case: Testing the FireFly® series optical isolation probe (1.5GHz high frequency, DC-180dB) recommended by PMK for VGS

For Vds testing, PMK's Bumblebee high-voltage differential probe (400MHz) is recommended; For ID testing, the recommended American T&M inductive coaxial shunt (400MHz~2GHz)

can be equipped with IWATSU Iwasaki Roche coils (optional high temperature resistance up to 150°C, finest wire diameter 1mm).

For mid- to low-end configurations, consider using domestically produced Zhixong optical isolation and high-voltage differential probes. Roche coils can use British PEM, allowing users to select according to budget and performance requirements

8. Heating Option (TO-247 Package).

The PD-200X integrated single-tube heating fixture is easy to use, safe, and reliable, supporting multiple temperature environments such as maximum temperatures up to 175°C

3. Three major system features:

1. Heating equipment

Jiechuang Instruments' patented product—device heating fixture, supports TO-247 package, easy and stable plug-and-pull, enables rapid heating (from room temperature to maximum temperature in just over 10 minutes).

Both the host and the PC host computer can be set up. In addition to common settings like 125°C, 150°C, 175°C, etc., any temperature from room temperature ~175°C can also be set

meets various application testing needs

2. Security protection

5mm thick visible safety protection box, security door equipped with sensor device + alarm light + program control software to achieve intelligent safety protection. When the user opens the door,

alarm light displays reminders, while the high-voltage power supply quickly steps down to ensure personnel safety

3. Program control module & host computer software

Pulse control, safety detection, and temperature control integrated module, combined with PC host software, makes operation safer and more convenient, eliminating the need for high-voltage power supplies and drivers

One-touch trigger to capture waveforms. PC side directly sets voltage start, pulse time, temperature, etc., with simple and convenient operation procedures

In summary, the PD-200X is a highly versatile dual-pulse dynamic parameter testing device, built on a modular system-level dynamic testing solution platform based on LEGO-like thinking

The system adopts flexible module interfaces and international standard signal transmission protocols to ensure data interconnection and interoperability, and compatibility between the testing instrument and sensor for high-speed signals

is consistent and traceable, offering repeatability. It is one of the industry's professional and efficient dynamic parameter testing solutions, especially suitable for the research, development, and performance evaluation of wide bandgap device SiC
