DC Electronic Load – Part 4: How Each Operation Mode Works with Other Modes?

We have so far explained the four major operation modes for electronic loads - 1) constant current 2) constant resistance 3) constant voltage and 4) constant power, in the previous white papers. Now this paper describes how these modes relate to each other and how each mode works on other modes. 4-1. Relationship between Operation Modes Figure 4-1 shows the block diagram for the control circuit ...

How to Double Output Voltage from Two PBZ through BTL* Connection

Here is an introduction on a method to achieve a double output voltage using two units of PBZ. The actual connection of PBZs is shown in Figure 1 as; -‘OUT’ terminals are used for output. - Only ‘COM’ terminal can be earthed for output, if required. For the frequency characteristics, it is limited to 50 kHz in CV (100 kHz in normal) and limited to 8 kHz in CC (10 kHz in normal) as speci...

Useful Functions and Precautions for Using L-Load/C-Load in PCR-LE Series

1. When Using Inductive Load (L-Load)1-1 Soft Start A typical L-load is a motor load. E.g.) If using an induction motor load, the startup current can be 5 times (or more) larger than the normal startup current and it flows for several hundred ms. In this situation; 1) The motor load becomes inductive. 2) The power factor is approx. 0.5 at peak current. PCR-LE Series features the Soft Start func...

Which Power Supply is Most Suitable to Run DC Motor?

When choosing a power supply to run a DC motor, the first and most important thing you need to consider is a maximum current that your motor will use. DC motor typically requires a startup current which is quite a lot higher than its running current. Due to this, not all DC power supplies can provide sufficient power to DC motors. In this white paper, we will take a look at the capability of our ...

How to Balance Battery Module Charge-Discharge

With the recent diversification of battery module application such as for automotive and backup, more and more users want to conduct a battery module charge-discharge test, besides of an individual cell battery test. As a battery management system has been greatly developed to maximize battery’s capacity, the practical needs to perform evaluations on balancing battery charge-discharge are incre...

DC Power Supply Sinks Current when Output is Turned Off

When using a DC power supply for charging a load such as battery or capacitor, it is important to note that the DC power supply absorbs a current from such loads when the output is turned off. Here we are going to further explain this power supply’s behaviour; DC power supply, in general, comprises a bleeder circuit to discharge a power supply’s electrolytic capacitor at its output terminal. I...

How to use the voltage correction function on frequency response

The PCR-WE can output up to 5 kHz, but it has frequency response as shown in the figure below. The response is about -3dB at 5kHz. For example, the waveform in the figure below is for 120 Vrms, 5 kHz. Voltage amplitude correction The PCR-WE has a function to correct the attenuation due to the frequency response of the output. Please refer to the “The soft sensing function is used” page...

DC Electronic Load – Part 1: What is a DC Electronic Load?

Beginners who have never used an electronic load may well get confused with the difference between electronic loads and power supplies. They sometimes wonder ‘why the electronic load does not provide any output...?’ While similar in appearance, electronic loads are totally different from power supplies. It is not often you get to see them but it is suitable for specific applications such as w...

Two Methods to Absorb Motor’s Regenerative Current Using Electronic Load

There are two methods to absorb motor’s regenerative current; Voltage Clipping Method and Bleeder Method. The following describes the characteristics, functions and precaution for the methods. Fig.1 illustrates the typical test system. 1. Voltage Clipping Method This method is to set the electronic load in CV mode to clip the motor’s regenerative current. If the regenerative current is...

Choosing Electronic Load that Best Fits Your Switch Testing System

The switch on/off testing can be performed with a combination of DC power supply and electronic load (See Figure 1). To successfully conduct the testing, it is important to know that the current flow through the switch varies by the electronic load specifications or settings. Especially during the life testing, you should be aware that it may affect the lifetime of test switch. This white paper s...

How to use the power line disturbance simulation function of PCR-WE

Voltage dips, short interruptions and voltage variations immunity tests of the IEC 61000-4-11 standard can be easily tested using the power line disturbance simulation function of PCR-WE. As an example, it explains how to set the voltage dip test. You can easily execute tests under the test conditions specified in the standard in a few steps. IEC61000-4-11 Voltage dip a Classes as p...
