BCM series

The intermediate bus converter BCM® series is a high power density, high efficiency isolated DC-DC converter with a fixed voltage conversion ratio (no regulation function).

The BCM series is available in two packages, ChiP and VIA packages. VIA packaged products have features such as PMBus™ control interface, EMI filtering, and transient protection.

The BCM series has a wide input voltage range of 48V-800V and various voltage conversion ratio K values, so it can be used for many applications.
High efficiency and high power density are achieved by using the unique switching method SAC® (Sine Amplitude Converter) technology.
By connecting in parallel, it is possible to handle high power, and by connecting isolated outputs in series, it is possible to output high voltage.
Due to the bi-directional conversion characteristics, by moving the capacitor placed on the low output voltage side to the input side, the large capacity capacitor required for the load can be reduced.

Intermediate bus converter with a maximum capacity of 1.95 kW "BCM6123" suitable for communications, industrial equipment, aerospace defense, etc.

The "BCM6123" is a compact CHiP package of 63.3 x 22.8 x 7.2mm, and is an isolated DC-DC converter with a maximum output power of 1950W and a maximum conversion efficiency of 97%. Parallel connection enables high power output, and series connection of isolated output enables high voltage output. Due to their high efficiency and high power density, they are suitable for applications such as communications, industrial equipment, and aerospace defense.

It has a very small package size of 24.8 x 22.8 x 7.2 mm, an input voltage range of 43 to 154 V, 14 to 72 V, 9 to 50 V, an output power of 35 to 120 W, and a maximum efficiency of 90.5%.

Their high power density, light weight, and easy handling make them suitable for a wide range of applications including robotics, UAVs, industrial equipment, railroads, communications, and defense/aerospace.

High voltage intermediate bus converter "BCM4414" with a maximum of 1.75 kW

The 800V compatible model of the "BCM4414" is one of the ultra-high voltage bus converter module "BCM4414 series", 110.55x 35.54x 9.4mm, maximum 1.75kW, output conversion ratio: 1/16 fixed, 500 to 800V primary side It supports an input voltage range and delivers a safe voltage (SELV) to the secondary side with a maximum efficiency of 97.7%.

Parallel operation is possible to meet higher power demands. In addition, by connecting the secondary output voltage in series, even higher voltage output is supported.

VTM™ Current Multiplier

VTM series

The "VTM series" is an isolated/non-isolated DC-DC converter with a fixed voltage conversion ratio, and is also called a current multiplier placed at the point of load (PoL). The VTM outputs a voltage isolated from the regulated primary side bus supply and supports a wide range of output voltages. Proprietary high-frequency (several MHz) ZCS/ZVS Sine Amplitude Converter (SAC™) technology achieves extremely high-efficiency, high-power-density voltage conversion to power loads that require large amounts of power.
