1. Overview
1.1 General Description
The HI-POWER series are configurable supplementary power products ranging from AC to DC. The
HIPOWER series provides a variety of modules with different output voltages and output currents. And
provide the most flexible and versatile solutions for medical and industrial applications. The HIPOWER
series provides accuracy, resolution and stability as a programmable voltage or current source.
The modular concept includes a HI-POWER rack into which HI-POWER modules are inserted.
The module inputs a programmable 3.2KW output power increment. The HI-POWER output module is
configured to construct a power system by inserting the module into a standard 19-inch rack. Each rack
can accommodate up to 8 modules (25.6KW), and higher power uses 2 racks in parallel to meet
customer needs. The HI-power series provides developers with an analog or digital interface to their
system, supporting standard communication protocols, including CANbus and RS485.
The HI-power series provides efficient power factor correction (PFC) and low total harmonic distortion
(THD)Wide load range. It uses an interleaved continuous mode boost PFC architecture and uses multiple
groups in parallel to reduce the stress of each group and enhance the stability and life of the system.
Users can configure and customize the HI-power module to meet the exact application requirements.
Qualified service personnel can configure the HI-power rack for single-phase or three-phase input.
Modules can be connected in series or in parallel, while realizing accurate voltage and current sharing.
Using group commands, modules can be controlled as a single output in parallel or series. For specific
types of load applications, the HI-power system can be programmed into three different compensation
configurations, including resistive load, capacitive load and LED load. LED load compensation has
opened up new applications for large horticultural farms that require the high voltage of many series
connected LED strings.

3.3.2 Output Blocking Diode and Antiparallel Diode Recommendation
The HI-power modules can be used in a redundant parallel system by connecting the outputs together
via OR-ing diodes. For good regulation the remote sense connections must be made after the OR-ing
diode at the same point on the busbar or load. The remote sense leads should be the same length for
each power supply and a twisted pair should be used for best noise immunity. The current share lines
between the power supplies should be connected as shown in Figure 3.5.

An antiparallel diode should be connected across each module’s terminal to prevent sinking of current
into one module when it is OFF while the others are ON. The diode should be capable of carrying the
maximum current and the forward voltage (Vf) drop should be lower than what is in the table below.
4. Digital Communication
Digital communication is necessary to setup and operate the HI-power system. Digital communication
will be used to:
• Read the configuration setting of the HI-power
• Change the configuration setting of the HI-power
• Voltage, current, temperature, and power reporting
• Status reporting
The communication with the HI-power system is controlled through the HI-power COMMD (isolated
communication) part of the power supply. All commands are sent to or from HI-power COMMD through
the digital communication link. After sending the command to HI-power COMMD, COMMD will process
and send the information to the internally installed module. COMMD acts as a bridge between HI-power
internal communication and HI-power external communication.
Inside the HI-power rack, there is an internal communication bus. The installed module and COMMD are
both connected to this internal communication bus but are electrically isolated from each other
according to safety requirements. COMMD manages the internal communication and external
communication of Hi-power. Once COMMD receives the user's command, COMMD will transmit the
command to the module. If the user needs data from the module, the module device will transmit the
data to COMMD, and COMMD will send the data to the user.
