An isolated DC-DC converter for high-voltage output voltage applications is presented in this paper. The proposed converter is specially indicated for application where there are necessary low volume and mass and high-efficiency (94%), operating with unregulated low input voltage. The main operation characteristics are soft-commutation in all power switches, constant switching frequency, PWM modulation and integration of the components intrinsic elements (distributed transformer capacitance, leakage inductance and power switches capacitance)
