Introduction
This chapter describes the general characteristics and main features of the FAST-
Bi-1K5 bipolar bidirectional and regenerative Power Supply (PS) series.
1.1
FAST-Bi-1K5 Overview
High performances, extreme stability, easiness of configuration as well as
bidirectional and regenerative characteristics are the key features of the FAST-Bi-1K5
power supply series.
The FAST-Bi-1K5 is an independent current- or voltage-controlled digital
bipolar, bidirectional and regenerative power supply module. Different models having
different current and voltage output ratings are commercially available, see Table 1; the
table reports also the classification between High-Current (HC) and High-Voltage (HV)
models.

FAST-Bi-1K5 standard models
The FAST-Bi-1K5 module is compact and fits in a single 19-inch 2U standard
crate. The PS (Power Supply) implements a completely digital control loop with a Pulse
Width Modulation (PWM) generation technique that allows adapting the system to any
load condition.
The control board houses a dedicated FPGA with integrated dual-core ARM
CPU. The loop regulation task is performed directly by the FPGA logic, in order to
have high performance and deterministic loop control. On the ARM CPU it is installed
