Offering configurable dual output voltages of +15V/-10V, +20V/-5V and +15V/-5V, the MGJ3 series of DC-DC converters is ideal for powering ‘high side’ and ‘low side’ gate drive circuits for IGBTs, Silicon and Silicon Carbide Mosfets in bridge circuits. A choice of asymmetric output voltages allows optimum drive levels for best system efficiency and EMI. The MGJ3 series is characterised for high isolation and dv/dt requirements commonly seen in bridge circuits used in motor drives and inverters.
