400V – 5A Power Supply For Brushless Motor Drivers
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...
