Half-Bridge Inverter with R Load
A half-bridge inverter is a basic power electronic converter that converts DC into AC using two switching devices (like MOSFETs/IGBTs) and a split DC supply.
🔹 Circuit Description
The DC input voltage � is divided into two equal halves using two capacitors.
Two switches (S1 and S2) are connected in series across the DC supply.
The load (R) is connected between the midpoint of switches and the midpoint of capacitors.
🔹 Working Principle
The switches operate in a complementary manner (i.e., only one ON at a time):
When S1 is ON and S2 is OFF
Output voltage across load:
When S2 is ON and S1 is OFF
Output voltage:
👉 This switching produces a square wave AC output.
🔹 Waveforms
Output Voltage (Vo): Square wave alternating between � and �
Load Current (Io):
Since load is purely resistive:
🔹 Key Features
Simple and cost-effective design
Requires only two switches
Output voltage is half of DC input
Suitable for low-power applications
🔹 Applications
DC to AC conversion (basic inverter systems)
UPS systems (low power)
Educational simulations & power electronics labs
🔹 Important Note ⚠️
Dead time must be provided between switching of S1 and S2 to avoid short circuit (shoot-through) of DC source. #eee #powerelectronics #electricalengineering
