BOP-MG BP-GL – Bipolar Power Operational Amplifiers
The BOP High Power are true 4-quadrant programmable voltage and current power supplies. 4-quadrant operation means that they are capable of both sourcing and sinking power. These bipolar power supplies pass smoothly through zero to provide ± voltage and ± current. The BOP High Power use switch mode technology for low dissipation. To maintain low dissipation while sinking power from an active load, the BOP High Power recuperate the energy for general reuse. The key to this is a bi-directional a-c input power factor correcting (PFC) circuit, which allows transparent energy interchange without dissipative sinking. The PFC circuit lowers the line harmonic distortion of the input current while maintaining a power factor greater than 0.97. The PFC works in both generation and recuperation modes.
The BOP High Power models produce up to 1000 watts of d-c power bi-directionally in nine MG models from ±6V to ±100V. The BOP 6-125MG (6V, 125A) is featured in Electronics Products magazine. Three GL models, optimized for very low ripple and noise, are available from ±10V to ±50V.
The BOP High Power models are controlled digitally from a front panel keypad or either of the built-in standard remote interfaces, either GPIB or RS 232, to set voltage or current and the four protection limits (+voltage, -voltage, +current and -current). A large LCD displays the settings, mode of operation and the actual output voltage and current. Additionally, the BOP High Power can be remotely controlled by an analog ±10V input. This mode is selected by the keypad from the menu, or remotely, through the IEEE 488 or RS 232 controller.
