Opt-Isolated Superfast, Super High-Power Switching Apparatuses
November 12, 2011, Louisville KY, USA, Electronic Design & Research, Inc. introduces the first of its kind: a super high-power switching apparatus (SHPSA-xx/vv) capable of delivering 800kW of energy in microseconds and tens of kilowatts continuously. Depending upon the components it is designed with, the apparatus works with either DC/AC voltage or DC voltage for a wide range of educational, scientific researches, industrial and defense related applications. Initially, it was devised to meet a growing demand for testing components that were used for manufacturing electric cars. In a short time, applications available for testing power supplies that provide short under- or overvoltage surges, military communication gears, and many other types of electronic equipment that are sensitive to power fluctuations. In reality, it is a high-power, high-speed push-pull or ½-bridge driver. .
The SHPSA includes two SPST switches, with help of the controller, were acting like a SPDT&N switch with a neutral or break-before-make state. The neutral state is an extremely useful property of the SHPSA that allows for the replacement of a load while applied voltages are still present on input terminals. Most remarkably, the device delivers almost perfect pulse-wave with rising and falling matching at speeds faster than 200nS with “G” switches and 15-nS “F” series switches, thanks to a superfast discharging capacitor array (SDCA-05). The device can be controlled by any lab generator. A built-in precision generator can be triggered by an external pulse or manually via a push-button for delivering a single pre-set duration pulse.
The controller (p/n EDR89002), designed for making both SPST switches function as a single SPDT Relay/Switch, provides several modes of operation:
1. A single shot (duration of the pulse is set by a built-in adjustable timer),
2. Push-poll or a ½ bridge driving mode with a frequency set by an external generator,
3. Pulse width modulation (PWM) of either switches,
4. Disable mode, in which the output is floating.
The SHPSA was designed as a versatile device. It can be assembled with SPST switches that worked with DC/AC or DC-only voltages. It can be used to test various power supplies, devices, and any other equipment for their susceptibility to an applied power. It can be used to test chokes, inductors, and transformers. The SHPSA is perfect as a pulsar in high-speed Capacitive Discharge Welding Systems. It is capable of providing short-duration weld pulses, enabling low energy welding and repeatable precise results with ultra-fast rise times for high-throughput weld cycles over a broad range of applications. It will find use in the particle acceleration, ultra-strong magnetic field generation, and fusion research fields, as well as providing power to high-power pulsed lasers and generating electromagnetic pulses.
The SHPSA's versatile design allows test of a wide variety of current devices, such as a resistor or a high-current chock, creating a pulse with various slope durations that could make it an invaluable tool in the fields of research and education.
Several devices (P/N EDR89001) of that family were delivered to MET Laboratories Inc., rated at 200V/400Arms (4000A pulse), and outfitted with a .5F super-fast capacitor array. Using already developed and tested technology, a number of systems can be assembled rated at different voltage, current, and the SDCA-xx.
