| contents | Power supply modules play a crucial role in modern power electronics by ensuring reliable and stable power delivery across a wide range of systems. In space applications, DC–DC converters are extensively employed to deliver regulated output power with high efficiency and operational stability. This paper focuses on the design and development of a dual-output forward converter operating at 140 kHz and implementing an input-voltage feedforward control technique. The UC2525 PWM controller is utilized for its features, such as, rapid transient response, soft-start capability, undervoltage lockout, and maximum duty cycle limitation. A Magnetic amplifier can also be used as a post regulator along with the Forward converter to improve the output voltage regulation and reduce the ripple (within permissible limit). The proposed system has been modeled and analyzed using LT Spice and TINA simulation tools. A hardware prototype is tested under different input voltages and load conditions at ambient temperature. Both Simulation and experimental results shows that the converter maintains stable operation, provides effective voltage feedforward compensation, and ensures accurate dual-output regulation, making it suitable for space applications. |
