Alternating current inverter, has smoothing capacitor substrate for mounting ceramic smoothing capacitors between isolated substrate and switch element driver circuit board

摘要

The inverter has switching elements (5a-5f) for inverting energy by switching, a driver circuit unit (6) for the switching elements, ceramic smoothing capacitors (2) for the output of a d.c. power source fed to the switching elements, an isolated substrate for mounting the switch elements, a driver circuit board and a smoothing capacitor substrate for mounting the capacitors between the substrate and driver circuit board.
