DC$-$DC Converter Design: Full Bridge H$-$Bridge with LTSpice

Objective:

Design and simulate a Full$-$Bridge H$-$Bridge converter that takes a $60$V DC input and delivers $10$ V across a $10-$ohm resistive load using LTSpice. The converter should operate efficiently while meeting the specified output voltage and current requirements.

Design Instructions:

Input Specifications:

Input voltage: $60VDC$

Input source: DC power supply

Output Specifications:

Output voltage: $10$ V DC

Load: Resistive load of $10$ ohms

Output current: $I=\frac{V}{R}=10\frac{V}{10}=1A$

H$-$Bridge Converter Design:

The converter should be designed using a Full Bridge H$-$Bridge topology. The H $-$bridge will allow you to control the polarity of the output voltage, converting the input DC voltage to a regulated DC output voltage.

Components required:

Four switches $($typically MOSFETs or IGBTs$).$ These switches will be controlled by pulse width modulation $($PWM$)$ signals to regulate the output.

Diodes for freewheeling, placed in parallel with the switches to handle the back EMF from the inductive load.

Inductor and$/$or capacitors if required to smooth the output voltage $($you may model them or assume an ideal DC$-$DC converter for simplicity$).$

Control Signals:

Design the gate driver circuit to generate complementary PWM signals for the four switches. The PWM duty cycle will determine the average output voltage.
