Power Electronics

Power Electronics is the study of switching electronic circuits in order to control the flow of electrical energy. It is the art of converting electrical energy from one form to another in an efficient, clean, compact, and robust manner for convenient utilization.

Modern power electronic converters are involved in a very broad spectrum of applications like switched-mode power supplies, active power filters, electrical-machine-motion-control, renewable energy conversion systems distributed power generation, flexible AC transmission systems, and vehicular technology, etc.

PLZ6000R is a DC electronic load that regenerates load power to the AC line. Regular electronic loads consume load power by having semiconductor devices convert it into heat. By contrast, PLZ6000R converts load power into reusable electric power, rather than converting it into heat as is typically done, and feeds this power to the AC line, thereby substantially reducing the amount of waste energy. PLZ6000R is an environment-friendly electronic load that can contribute significantly to your energy saving efforts.

plz-u-300x206Modular Multifunction DC Electronic Load (CC/CV/CR/Zero volt input) : 4 Models

Outline

The current trend in semiconductors is towards lower voltages and higher speeds. This trend places similar demands on both the components of semiconductor power units, such as switching power supplies, batteries and DC/DC converters, and also on the electronic loads used for testing. Also, a growing number of users with a need for multiple-output power units and easy channel reconfiguration are calling for plug-in type electronic loads that can be easily configured to support multiple channels. The advent of an electronic load system that satisfies all these needs has been long awaited. It was against this background that we developed the PLZ-U Series of electronic loads.
The PLZ-U Series of compact and high-performance modular electronic loads is capable of operating in five modes: constant current, constant resistance, constant voltage, constant current + constant voltage, and constant resistance + constant voltage. The load system consists of load modules and a frame. The load modules are inserted into the frame that also serves as a control unit. The PLZ-30F frame can accommodate up to three load modules, while the PLZ-50F frame can accommodate up to five. The load modules can be operated in parallel, so that the current capacity or power capacity can be changed easily, from 75 to 750 watts*1, as needed for the device under test. In addition to offering high-speed response at a maximum slew rate of 2.4 A/ µs*2 and a minimum setting resolution of 10 µ A*3, the system features a variety of functions including soft start, variable slew rate, a switching function, ABC preset memory function, four setup memories, and a sequence function. What’s more, timer functions combined with time/voltage measurement functions allow you to measure battery discharge characteristics.
For communication, the system is provided with GPIB and RS-232C interfaces as standard. Both interfaces support IEEE 488.2 as well as the Standard Commands for Programmable Instruments (SCPI) commands, developed for testing and measuring instruments.

    The electronic load system is as wide as a 19-inch rack with a height of 3U. Weighing about 11 kg when configured for three channels or about 17 kg when configured for five channels, the system is compact, lightweight and space-saving.
  • High-speed response
    In constant current mode, the electronic load is capable of offering high-speed response at a slew rate of 2.4 A/µ s at the rising and falling edges of the current (equivalent to about 10 µ s when converted to the rise and fall times; in the case of PLZ150U).
  • High precision and high resolution
    The built-in three-range configuration provides both wide dynamic range and high precision. The voltmeter, ammeter and wattmeter functions that display values using up to five digits each and a minimum setting resolution of either 10 µA (PLZ70UA) or 20 µA (PLZ150U) are implemented.
  • Variable slew rate
    In constant current or constant resistance mode, the slew rate can be changed continuously.
  • 0(Zero)V input
    The PLZ70UA model operates even when the input operating voltage is 0(Zero)V.
  • Multi-channel system
    PLZ-50F may be configured with up to five channels, and PLZ-30F may be configured with up to three channels. Isolated from each other, the channels can operate both independently and in synchronization. Different models of load units (PLZ150U and PLZ70UA) can be housed in a single frame.

The PLZ-5W Series high performance electronic load is the successor to the highly respected PLZ-4W series, whilst still retaining the same high specification and build quality. Advances include a high visibility color display, low voltage operation from a minimum of 1 V to a maximum of 150 V. Programmable profiles of voltage/current can be applied (using the new ARB function, as used in LED/solar testing) in addition to the inherited 6 modes of operation: Constant Current, Constant Resistance, Constant Voltage, Constant Power, Constant Current + Constant Voltage, Constant Resistance + Constant Voltage.

Features

  • Color liquid crystal display (LCD)
  • Maximum Slew Rate of 60 A/μs
  • High speed voltage tracking characteristics
  • Communication interfaces are included as standard
  • Multiple units of the same type can be connected in parallel. Without using boosters, you can connect up to five units of the same model in parallel, including the master unit (max. 6 kW, 1200 A)

pia4850-300x206Power Supply Controller with USB

Outline

The PIA4850 is a power supply controller with USB interface to control Kikusui DC power supply with TP-BUS. PAS Series, PWR Series or other models that equips TP-BUS can be digitaly controled by PC, as well as for read-back of output values and status monitoring. It operates using bus power and with its simple system and compact structure, you can use whenever you need with easy setup.

Features

  • USB 2.0 compatible
  • Can be used with Windows Vista/XP/2000.
  • Operates using bus power. Requires no AC adapter.
  • Bus power operation. No AC adapter required.
  • Allows read-back of output values and status monitoring.
  • Can control up to 32(*1) DC power supplies that equip TP-BUS(*2).
    (Different power supply models can be combined.)
    TP-BUS connection can be extended up to 200 m. Ideal for remote monitoring !

pia4800-300x206Power Supply Controller Supporting Multiple Channels : 5 Models

Outline

The PIA4810 is a power supply controller capable of analog and digital control. It is equipped with the GPIB and RS-232C interfaces and 4 slots, which allow 4 each of PIA4800 Series-specific control boards to be installed. A control board is capable of analog control of 2 channels of DC power supplies or electronic loads; a total of 8 channels can be controlled.
Moreover, DC power supplies with a digital remote-control function, such as the Kikusui PAS, PAM(*1) and PMR Series, can be directly connected to the PIA4830 via a TP-BUS (twisted pair bus), enabling a system up to 32 channels to be controlled digitally.
