Title:
コンバータの改良
Document Type and Number:
Japanese Patent JP4796728
Kind Code:
B2
Abstract:
A converter for high voltages includes a bridge circuit having serially arranged switching assemblies so connected as to define at least two input notes and two output nodes. The input nodes are adapted to receive an input voltage across the input nodes, and the output nodes are adapted to provide a take-off point for the output waveform. A control circuit supplies a respective control signal to each switching assembly in the bridge circuit. A resonant circuit is connected across the output nodes. The devices are switched at the resonant frequency of the resonant circuit. Thus, by switching as the current crosses zero in the resonant circuit, sudden rises in voltage across the devices are avoided.
