Resumo: | This work proposes a new strategy to improve the double-output DC-to-DC converter. The isolated full-bridge topology is zero-voltage switched (ZVS) and the pulse-width modulation is phase-shifted (PS-PWM). The high-frequency isolation transformer has two secondary windings to feed both the +220V and -220V DC outputs. The output filtering inductors are coupled together to balance the output voltages. A very simple command circuit, using only one integrated circuit, is employed to obtain regulated DC outputs and to drive the switches. |
