I use maintly with my trainees this expression
The difference between Electronics and Power Electronics is that of between a sea and an ocean !
What really makes the difference is the scale of the physical parameters dealing with in each field specifically the Ampere and the Voltage
Power Electronics is related to Higher Voltages 220 or above.
Electronics is related to lower voltages devices operations upto 30 volts.
They are all electronics but power is one part of electronic, which foucuses on voltage and current of the signals. also power managment process e.g. AC to DC conversion and DC to DC managment e.g. stepping up and stepping down voltages.
Power electronics refers to device used in switch mode: Electrical osses in the best case appear only during the switching from on-state (low Voltage - High current) to the off-state (High voltage - no current). In general this is achieved at relatively low frequency. In Analog electronics the device are used in general following sinus(t) signal. Various classes of operation are used (e.g. A, AB, B, C) which are associated with dissipated powers. In analog electronics one try to use also devices in switch mode (class D, E, F, S) but this is difficult to be achieved as the frequencies rise. Analog and power electronics are 2 different worlds, but there are bridges between them.
Power Electronics is a Branch of Electrical. But the Electronics components used for High power Conversions and Inversions of Electrical Power, Some of Power Electronic Components are SMPS,ONLINE UPS,OFFLINE UPS,3 PHASE PWM INVERTERS,VFD,AVR,..
je crois que c'est une branche ou un module intégré avec le monde vaste de l'électronique, mais elle est utilisée, généralement, dans l'étude d'alimentation des différents cercuit électronique.

Power Electronics is the sub branch of electronics.Power electronics deals all the power controlled devices and power control techniques. You can find many applications of power electronics around you like Motor drives, Chargers, UPS systems, Power Supplies etc.
Electronics in general is a study that deal with the behavioral flow of electrons in a certain medium. But if we classify electronics to power electronics, electronics deal with low power devices such as ordinary resistors, capacitors,op amps, etc. While in power electronics, we will be dealing with high power devices and also with magnetism. Because magnetism occurs and very evident when there is a high power that leads to a high current flow within the medium. Thus the electric field and the magnetic field is being studied rigorously.
Electronics is no more a single subject of study anymore , nowadays there are multiple branches of electronics and they have their own Major Faculties. The basic branches are -Telecommunications / AV Consumer Electronics / Power Electronics / Computer Applications & Digital Electronics / Security & Survelance Electronics / Automotive Electronics etc. to name a few.
Power Electronics is the branch of electronics which deals in Electrical Power supply / Energy related applications both in the Industrial and Home domains , this field covers Power Solutions / Generation / applications / Appliances and Devices / Transmission / Consumption & Conversion etc. covering any source where electrical energy is required. This is a mojor branch in Electronics Engineering.
The Term Electronics is a general nomenclature for study of Semiconductors and their applications. Electronics Engineering cannot be clubbed into one subject today.
