Thanks to very fast and accurate control and management of all parameters by microprocessors and special microcontrollers in this type of power supply, it seems extremely high energy consumption efficiency, exemplary output ripple control, very precise voltage regulation (less than 1%), and transient responses are very fast.
Transformer with Flat Wire Winding technology
OCDG series power supplies are equipped with high-efficiency transformers with flat wires. These types of transformers have much less magnetic leakage and occupy much less volume than conventional models at high frequencies. Also, in transformers equipped with flat wires, due to the increase of the skin effect at high frequencies and the tendency of electrons to pass through the outer layers of the wire, the AC resistance will be much lower than the models equipped with round wires. This will reduce heat loss and also increase the energy efficiency of the transformer.
High-efficiency MOSFETs with low-RDS in DC-DC converters
OCDG power supplies owe much of their ultra-high energy efficiency to their high-speed switching MOSFETs, low-RDS, and ultra-low leakage currents in their secondary DC-DC converters. This ultimately results in extremely cool performance and a very long lifespan of this series of green power supplies.
Super high quality Japanese capacitors in the initial part
The 1200 watt and 1350 watt models in the OCDG GREEN series power supplies are equipped with two 820uF (1640uF) capacitors with extremely high quality and, of course, the expensive MXK series made by the Japanese company Rubycon. Among the features of this type of capacitor is the long life of 3000 hours at 105 ° C and very low ESR. Also, this high volume of capacitive capacity in the initial part of the ripple will have a very low output and also a guaranteed Hold-Up Time beyond the standards. Meanwhile, for the power of 1050 watts of the same series and in proportion to its output power, two high-quality 680uF (1360uF) capacitors of the MXH series made by the Japanese company Rubycon have been used.
High quality Japanese high quality electrolytic and solid capacitors in the secondary section
In the secondary part of OCDG series power supplies, electrolytic capacitors (Nippon Chemi-Con) made in Japan and solid capacitors (Nippon Chemi-Con and NICHICON) made in Japan with the ability to operate at 105°C and very long life are used. These capacitors, which are in fact part of the filter circuit and the ultimate refining of output voltages, while stabilizing the long life of the power supply in the most difficult conditions, will improve the power performance in the ripple section and output noise.
Cable-less Design circuit design
In none of the power transmission sections on the OCDG GREEN series power supply board, no wire is used and the current transfer from the input of the main board to the output of the board related to the cable connections is considered only by the copper lines of the printed circuit board. So that even the board of the Cable Management section of OCDG power supplies is connected directly to the mainboard and its soldering operation is performed. This not only minimizes mass production errors, but in practice reduces energy losses, does not disturb the air circulation inside the power supply, and also increases the purity and quality of the output voltages.
Digital control of banks by a dedicated microcontroller
Online management and control of all OCDG series power supply parameters are performed by a dedicated microcontroller. This digital control ultimately improves the transient response of output voltages, increases energy efficiency, reduces ripples and noise, and stabilizes output voltage levels as much as possible.
Modern Half-Bridge topology with LLC Resonant converter in the initial section
In this series, thanks to the modern and highly efficient Half-Bridge topology along with the LLC Resonant converter, which softens the switching wave shape (Soft Switching) and the practical implementation of Zero Voltage Switching at the input, EMI, RF carriers, and switching losses at the input are reduced. Findings and energy efficiency (Efficiency) increase significantly. Also, the Resonant Tank Converter (LLC Resonant) allows the switching speed of the input MOSFETs to be much higher than the previous generation topologies, which in practice, especially in the case of idleness, increases energy consumption (efficiency).
Voltage regulation less than 1% for main output Rails 3.3V,5V and 12V
The use of DC-DC topological converters to generate 5V and 3.3V voltage in the secondary section stabilizes the output rails as much as possible in this series of power supplies. Also, the independence of the main parts of voltage control and management of each output rail in the power supplies equipped with this topology in the secondary section, their correct and accurate operation in the state of no-load (Zero Load) and Guarantees Cross Load (unbalanced distribution of load on output rails).
Faster and more accurate performance of safety protections
The monitoring chip in modern switching power supplies is the most important part of monitoring all the interactions performed in it. OCDG series power supplies use a newer and more accurate Supervisor chip than previous generation models and provide extremely precise digital control, in a much more closed and accurate range for controlling OCP, OPP, and OTP protections.
Fully modular cabling management system with HCS + connectors with gold plating and 150% more current throughput
All-flat cables and the ability to manage all-modular cabling This series of power supplies will play a decisive role in the faster, more elegant and professional assembly of your system. While in new generation platforms due to the introduction of processors with more cores as well as more power consumption (TDP), motherboard manufacturers, especially in high-end and expensive models, use power connectors in the motherboard class called HCS + (High Current System) server. . These connectors have an average of up to 150% more power to pass current. The new OCDG series power supplies use gold-plated HCS + samples in both the male and female sections in the modular connectors section. In this type of connectors, they increase the operational level and use a much more resistant alloy against high currents in reducing ripple, voltage drop and connection point, and in general, they will increase the stability of the system in overclocking and gaming applications.
Completely modern and efficient cooling system with the ability to select fanless mode
The second-generation OCDG power supplies are equipped with high-quality fans and in industrial application classes with FDB technology. FDB fans, which are currently one of the most modern bearing systems, have an even longer life and, of course, much less acoustic noise than Double Ball Bearing fans. OCDG power supplies also have a digital point controller sensitive to both points inside the power supply and the amount at the power output. This fully intelligent circuit controls and manages the fanless status (at an output load of less than 25% of rated power) and the fan rotation speed in different conditions by analyzing the lines mentioned by the digital microcontroller. In addition, a special switch built into the back of the power can be activated or deactivated by Fanless mode.
