This paper considers the design of a "long-pulse" modulator supply rated at 25 kV, 10 A (250 kW peak power, duty ratio 10%, 25 kW average power, pulse length ≈ 1 - 2 ms). The supply is based on direct modulation of a multi-phase resonant power supply, fed by an active rectifier. The objectives of the development are to produce a compact power supply, with low stored energy and with high power quality at the utility supply. The paper provides a brief overview of the technology, followed by a discussion of the design choices. Initial results from the laboratory prototype are included.
