OG exemplary drawing
 
1. A power module, comprising:
a heat-dissipating substrate;
a first planar power device comprising a plurality of electrodes which are all on an upper surface of the first planar power device;
a second planar power device comprising a plurality of electrodes which are all on an upper surface of the second planar power device, and the first planar power device is electrically connected with the second planar power device in series to form a series branch;
a first capacitor being electrically coupled with the series branch in parallel;
a switching device comprising a plurality of electrodes, the switching device is coupled with the series branch;
wherein a lower surface of the first planar power device and a lower surface of the second planar power device are disposed on the heat-dissipating substrate.
 
17. A power converter, comprising:
a power module of claim 1;
a power input terminal connected to the power module; and
a power output terminal connected to the power module; wherein the power input terminal receives an input voltage which is converted by the power module into an output voltage outputted through the power output terminal.
