Plasmasonic Half-Bridge Assembly

Plasmasonic DRSSTC Half-Bridge Assembly

The half-bridge assembly is comprised both of a voltage-doubler rectifier power supply and a half-bridge switching circuit using a CM300 600V or 1200V, 300A IGBT module. This circuit takes the incoming AC voltage and through a voltage doubler circuit can output a DC bus voltage of up to 700VDC when using the appropriate AC input voltage and DC rated capacitors.

The polycarbonate DC capacitor support assembly provides mounting for a standard AC muffin fan as well as two Powerlytic 36DX DC bus capacitors. The base of the polycarbonate DC capacitor support assembly has three (3) 10-32 threaded inserts which can be used to secure the assembly to a base.

The heatsink assembly has two (2) 10-32 threaded grounding points, one which can be used for grounding a primary shunt capacitor, a 10-32 threaded attachment for a standard GBPC35xx bridge rectifier module, and 1/4-20 threaded mounting holes for a CM300 IGBT module. The base of the heatsink assembly has two (2) 10-32 threaded hole which can be used to secure the assembly to a base.

Connecting the DC bus capacitors to the CM300 IGBT module is a 0.124" thick laminated bus bar utilizing an effective 6 oz. of copper. There are two low current safety bleeder / balancing resistors across each DC bus capacitor which are soldered directly to the laminated bus bar.

The half-bridge assembly is available in two variants. One is designed for using 600V, 300A CM300 IGBT modules and the second one is designed for using 1200V, 300A CM300 IGBT modules.
