It is a pulse converter for different devices battery supply. The converter uses a choke on core E65, which inductance is about 1mH, 30A/1200V IGBT transistors and corresponding diodes. Frequency of the operation of the converter is approximately 30kHz. Maximum output current 15-16A at a voltage up to 750V DC. Presented here device is two-phase converter with two chokes, transistors and diodes per phase. All the semiconductors were mounted on one heat sink and isolated from it using ceramic elements. Driver SG3256 operate in a standard application. Overvoltage protection prevents the converter in the case of detecting even a short pin of voltage exceeding the preset threshold. Artificial load was made of a heater.
