Although the power supply design is specific to the Brushless Servo Drivers mainly for IPM Modules, the concepts and circuit design may be used for any power supply requires high voltage output up to 400V DC and 5 Amps. The power supply is an unregulated design with an option to allow connection to either 120V or 230V mains and also it can work with lower voltage for audio amplifiers by increasing capacitor value. The design uses fully integrated bridge rectifier, and multiple bus capacitors for low ripple, noise suppression, and provides high current reservoirs. Additionally the dc supply line have bleeder resistor R2 and R3 to drain the large reservoir capacitors PCB, mounted fuse holder provided  for short circuit and over current protections, low ohm NTC used for inrush current at power start up,  C1, C12, TX protects  against turn on/off spikes and EMI noise reduction. This power supply can be used to drive Tesla Coils, Induction heaters, DC Motor drivers, Brushless DC motor driver.

Note: Two BOM provided for supply up to 120V AC and BOM 2 for supply input up to 230V AC

Additional precautions must be taken as this power supply uses lethal voltages. Build it only if you know what you are dealing with.

Features

  • AC Supply input up to 120V AC
  • Maximum DC Output 400V DC and 5Amps.
  • 230V AC Input possible with few components value alteration
  • DC Supply Output will depend on input supply
  • Fuse for Short circuit and over current protection
  • Fuse as per your application requirement Maximum 5Amps Fuse
  • NTC provided for inrush current
  • DC Bus has bleeding resistor

    Could you indicate a part number or specs for T1? Does T1 provide any isolation between input and output?

      We are sorry, we don’t sell kits or assembled boards. If you need one piece you will have to build it your own.

    can i use for 3 phase motor control?

    • This is just a 400V/5A power supply and can be used on a Motor Control Board that requires such voltages.

    hello,
    May i know what difference Gnd and -V on circuit. Where to connect gnd actually in circuit.Thanks

    • GND is the reference (0V) for the positive +V and negative -V voltages produced.

    please can you explain the function of C13 and why there is a Ground-Terminal on the output? because i think you cannot get energy between V+ and GND or V- and GND.

    • This capacitor required to protect the IGBT/MOSFET when used in Tesla coil projects. The capacitor is replaced by inductor when its used in induction heating applications. You can surely get energy between V+ or V- and GND. Please note this is the system GND and not mains EARTH.

        Have you got an MOQ?

        8 months ago
        • Yes, as we don’t have these in stock and usually don’t sell kits or assembled products, we have to manufacture them for you. So our MOQ is 25 pieces.

            Thank you Mike,
            So how much would 25 boards be and 25 kits?
            Thanks,
            Graeme
