    Bipolar power supplies Unipolar and bipolar power supplies Unlike with resistive loads, when a power supply that alternates voltage polarity based on time is applied to an inductive or capacitive load, the current phase becomes Unipolar power supplies lagging or leading to the voltage phase. (First- and third-quadrant operation) If this occurs, there are four possible combinations of the voltage and current polarities.

  • Page 34: Operation Modes

    Operation Modes The PBZ has the following two operation mode settings. You can specify each setting individually. ● Bipolar/unipolar mode In bipolar mode, the PBZ operates as a bipolar power supply. In unipolar mode, the PBZ operates as a power supply that generates positive voltage and positive and negative (source and sink) current.

  • Page 35: Cv/Cc Mode

    Operation Modes In these situations, if you set the PBZ to unipolar mode, you can greatly reduce the output amplifier’s internal loss. As a result, the PBZ’s operating range in the second quadrant will be expanded to its rated values. Example of a battery load The PBZ is in unipolar mode in the figure below.

  • Page 36: Circuit Configuration

    Circuit Configuration The PBZ is designed so that you can select either an internal or external signal source. Then, the selected signal is fed to an output amplifier, and the amplified signal is generated. To make it easier to understand the operations explained in the following sections, the figure below shows a block diagram of the PBZ circuits.

  • Page 52: Using External Control Signals

    Using External Control Signals You can control the DC signal by using voltages that are from 0 V to approximately ±10 V or by using 10 kΩ variable resistors. Before using this function, you have to use CONFIG change some settings. In the figure below, control voltage or variable resistors are indicated as “Control signal J1.”...
  • Page 53 Using External Control Signals Connect a low-noise, stable voltage source to Vext. To reduce the influence of noise on the output, connect a two-wire shielded cable or a twisted pair cable across Vext, and connect the voltage source so that it is as close to the PBZ as possible. If the wiring between the PBZ and the voltage source is long, it becomes easy for noise to influence the operation of the PBZ.

  • Page 54: Using External Resistance

    Using External Control Signals Using External Resistance You can control the internal signal source’s DC signal by changing the reference voltage’s voltage-divider ratio through the use of external variable resistors. In CV mode, you can control the voltage. In CC mode, you can control the current. The output is equal to the sum of the value that is determined by the external resistance and the DC values that are set from the panel and remote control.

    Sequence Feature You can use the sequence feature to automatically execute the steps that you have set in advance. You can sequentially update the internal signal source settings, so you can perform a variety of waveform simulations. The sequences that you create are saved to non-volatile memory, so they are not lost when you turn the PBZ off.

    Controlling DC Signals (The DC Settings) You can control the DC signal by using voltages that are from 0 V to approximately ±10 V or p. 87 by using 10 kΩ variable resistors. Before using this function, you have to use CONFIG change some settings.

  • Page 137: Using External Resistance

    Controlling DC Signals (The DC Settings) Using External Resistance You can control the internal signal source’s DC signal by changing the reference voltage’s voltage-divider ratio through the use of external variable resistors. In CV mode, you can control the voltage. In CC mode, you can control the current. The output is equal to the sum of the value that is determined by the external resistance and the DC values that are set from the panel and remote control.

    Turning Output On and Off Uses external control signals to turn the OUTPUT terminal’s output on and off. You can also use switch contacts. If you are using external control signals to turn the OUTPUT terminal’s output off, you cannot use the panel’s OUTPUT key or remote control to turn output on.
